Materials Testing Machine (ME-8236)
Materials Testing System (ME-8230)
Comprehensive Materials Testing System (ME-8244)

Introduction

The Materials Testing Machine is a device for measuring force and displacement for various materials as those materials are stretched, compressed, sheared, or bent. The machine has a built-in load cell (strain gauge transducer) capable of measuring up to 7100 N (1600 pounds) of force, as well as an optical encoder module that measures displacement of the load bar. A crank- and-gear system raises or lowers the load bar on two leadscrews. Force data from the load cell and displacement data from the encoder module can be recorded, displayed, and analyzed by PASCO Capstone data collection software with the aid of a PASPORT interface.
NOTE: SPARKvue data collection software should not be used with this apparatus.

Tensile sample information

Tensile samples (ME-8231 through ME-8235 and ME-8243) are included with the Materials Testing System and are used for tensile strength testing. The samples include four metals (aluminum, brass, annealed steel, and steel) and two plastics (acrylic and polyethylene). All of the tensile samples have an overall length of 90 mm (3.5 inches). The center section of each sample has a diameter of about 3.3 mm (0.131 inches). The threaded ends are metric M12 x 1.75. The samples can also be ordered separately in packs of 10.

The table below shows typical values of tensile strength and Young’s Modulus for the provided tensile samples.

*Tensile strength values for plastics depend on the rate at which the sample is stretched. Provided values were recorded with speeds of <5 mm/min; measured values may vary significantly at higher speeds.
Setup
Setting up the Materials Testing System involves securing the machine to a sturdy support and setting up data collection in PASCO Capstone.
CAUTION: Always wear adequate eye protection when using the Materials Testing Machine or its accessories.
Securing the Materials Testing Machine
There are two holes through the base of the Materials Testing Machine that can be used for bolting the machine to a sturdy support. The two 6 mm diameter holes are 15 cm apart, with one on each side of the label, as shown in Figure

Bolting the machine down will avoid the problem of the apparatus moving during a sample test. The Materials System Storage Base (ME-8229) is designed for two purposes: to provide a sturdy base to which the machine can be bolted, and to serve as a storage place for accessories, tools, and other items in the Comprehensive Materials Testing System. The Storage Base includes two screws and two washers and has two threaded holes matching the spacing of the holes in the Materials Testing Machine base. To install the Storage Base:

1. Place the Materials Testing Machine onto the Storage Base, aligning the holes in the machine’s base with the threaded holes in the Storage Base.
2. Place the washers onto the screws.
3. Insert one of the screws into a hole in the base of the machine, and into the threaded hole in the Storage Base below.
4. Tighten the screw using your fingers.
5. Repeat Steps 3 and 4 for the other screw.
6. Use a 7/16 inch (11 mm) wrench to secure the screws in place.
7. Recommended: Use C-clamps (not included) to fasten the Storage Base to a sturdy table or bench.

The Materials Testing Machine and Storage Base can also be bolted directly to a table or bench, as shown below. The Storage Base has through holes at each of its corners to allow this type of connection.

Software setup
Follow the steps below to connect the Materials Testing Machine’s sensors to the PASCO Capstone data collection software.
To connect the apparatus to PASCO Capstone:

1. Turn on Capstone, then click Hardware Setup from the Tools palette.
2. Connect the AirLink (PS-3200) or another chosen PASPORT interface, such as the 850 Universal Interface (UI-5000), to Capstone. For instructions on doing this, see the interface’s manual or the Capstone online help.
3. Plug the sensor cable on the apparatus into a PASPORT port on the interface. The program will automatically detect and recognize the Materials Testing Machine.

To set up data collection:
PASCO provides Capstone workbook files containing various pre-configured experiments for use with the Materials Testing System and its accessories. A list of these labs can be found at www.pasco.com/resources/lab- experiments/collection/35.
Calibration
If the Materials Testing Machine were perfectly rigid, it would always give completely accurate measurements of force and displacement during compression or tension experiments. However, the machine is not perfectly rigid and will “flex” slightly while in use. To correct for this, we can perform a calibration procedure which will characterize the stiffness of the machine and perform a calculation to adjust the raw position data, leaving only the displacement that is due purely to the distortion of the test sample. This “compliance calibration” information can then be stored within the machine or in a Capstone file. Compliance calibration should always be applied during an experiment! The calibration rod and nut can be used for calibrating the machine for compression or tension. The calibration rod will not change shape significantly under tension or compression. This means that any displacement measured when using the rod is due to the flexing of the Materials Testing Machine itself. For example, the sample graph below shows that the machine flexes by 0.2 mm per 3600 N of force when the calibration rod is being stretched. When using the machine to stretch a sample, the “flex” amount of 0.2 mm per 3600 N needs to be subtracted.

NOTE: PASCO provides a Capstone workbook file walking the user through the process of creating a compliance calibration. To download this lab, go to www.pasco.com/resources/labexperiments/collection/35 and select Compliance Calibration Tutorial.
Mounting the calibration rod
To mount the calibration rod for tension:

1. Screw the short-threaded end of the calibration rod into the top of the load cell.
2. Lower the load bar until the threaded part at the top of the calibration rod goes through the hole in the bar.
3. Screw the load bar round nut onto the top of the calibration rod. (See Figure 3.)
4. Attach the Velcro® hook material on the two safety shields to the loop material on the front and back of the load bar. Adjust the shields’ position so that they will block any fragments of the calibration rod if it accidentally breaks.

To mount the calibration rod for compression:

1. Screw the short-threaded end of the calibration rod into the top of the load cell.
2. Screw the calibration nut onto the top threaded part of the calibration rod until the nut is at the bottom of the threaded section.
3. Lower the load bar until the bottom of the bar rests on the top of the calibration nut.
4. Attach the Velcro® hook material on the two safety shields to the loop material on the front and back of the load bar. Adjust the shields’ position so that they will block any fragments of the calibration rod if it accidentally breaks.

Optional: Changing sign

By default, the Materials Testing Machine treats the force and position values recorded during tension force experiments as negative. While it is possible to use the machine with these negative values for force and position, it is more convenient to change the sign convention to be positive before calibrating the sensor for tension experiments. To do this:

1. Select Hardware Setup from the Tools palette.
2. Click the Properties icon next to the sensor’s name.
3. The “Change Sign” box in the Properties window is unchecked by default. This means that there is a positive value for both position and force when the load bar is moving down, as in a compression experiment. For tension experiments, check this box to enable sign changing.
4. Click OK to exit the Properties window.

Calibration options
To access the calibration options, select Calibration from the
Tools palette. Ensure that Materials Testing System:
Compliance Calibration is selected as the measurement type to be calibrated, then click Next. This will present you with a series of five options, as shown below.

• Create New Calibration: Create and save a new compliance calibration.
• Use Calibration: Enable a compliance calibration loaded into the Capstone file. If the dropdown menu is blank and inaccessible, there are no saved calibrations in the file.
• Import Calibration From Sensor: Import a compliance calibration stored on the sensor into the current Capstone file.
• Use Raw Values: Temporarily disable compliance calibration for the experiment.
• Manage Existing Calibration: Rename or delete a compliance calibration stored in the file, or upload it to the sensor.

The following sections will explain some key uses of these functions.
Create a new calibration

1. From the calibration options, select Create New Calibration and click Next. A Graph display tracking Position versus Force will automatically be created.

2. If you have not already done so, set up the apparatus for calibration, following the instructions from the appropriate section of Mounting the calibration rod. Ensure the bar is at a position where it is not yet exerting a force on the rod.

3. Click Next.

4. When you are ready to begin collecting calibration data, click Record . The program will automatically begin recording position and force data from the apparatus.

5. Rotate the crank to begin causing the load bar to exert a force on the calibration rod. For tension tests, rotate clockwise to move the bar up. For compression tests, rotate counterclockwise to move the bar down.

6. Once your calibration has covered the full range of force values which you expect to use in your experiment, click Stop to end data recording. The Graph display will automatically plot a best fit curve of the collected data.

7. Click Next.

8. The program will now display the Curve Fit Editor, allowing you to adjust the best fit curve for the data. If desired, you can change the number of terms, enter an “Initial Guess” for each coefficient, and lock or unlock a coefficient value.
   NOTE: If the curve fit was not successful, use trial and error in the Curve Fit Editor to adjust the coefficients until the curve fit is successful. Click Update Fit to view the impact of the new coefficients.

9. Once you receive a message saying “Curve fit was successful”, click Next.

10. Name your compliance calibration, then click Finish.

Once a new compliance calibration has been created, you can apply it at any time from the calibration options by choosing Use Calibration, selecting the name of the new calibration from the dropdown list, and clicking Finish.
Import an existing calibration

1. From the calibration options, select Import Calibration From Sensor.
2. Open the dropdown list and select the name of a compliance calibration stored on the sensor.
3. Click Finish to import the selected calibration to the current Capstone file.

The sensor can store up to four compliance calibrations at a time. Any “slots” not containing calibration data will be listed as “Empty Calibration” followed by a number from 0 to 3.
Store a calibration on the sensor
After creating a new calibration, you can store this calibration on the sensor using the following steps.

1. From the calibration options, select Manage Existing Calibration, then click Next.
2. Ensure that the calibration you wish to upload is selected in the new dropdown box.
3. Select Save Calibration In Sensor and click Next.
4. Using the new dropdown box, select which calibration slot you wish to overwrite with the new calibration.
5. Click Finish.

Tension force data collection

Once you have a successful compliance calibration, you may begin collecting data using the Materials Testing System. One of the simplest and most accessible experiments that can be done with the machine is tensile strength testing, which only requires the machine itself, a tensile sample, and the load bar round nut.
Mounting a tensile sample

1. Select a tensile sample, then place the end of the sample with the shorter threaded section into the threaded hole in the top of the load cell.
2. Screw the sample into place until the top edge of the short threaded section is flush with the top of the load cell.
3. Using the crank handle, lower the load bar so that the longer threaded section of the sample goes up through the hole in the center of the bar.
4. While holding the tensile sample so it does not turn, screw the round nut onto the longer threaded section until the sample is held tightly in place.
5. Attach the two safety shields to the front and back of the load bar. Adjust the shields’ position so that they will block any fragments that may come from the sample.
6. Turn the crank handle clockwise to raise the load bar until you begin to feel resistance, then turn it back counterclockwise by about a quarter turn.

Seating the sample and setting a pre-load
In order to obtain the best possible data, a test sample should be slightly stretched and relaxed to properly “seat” the sample, removing any slack, and a pre-load should be set.

1. In Capstone, create a Graph display of Position versus Force, as well as a Digits display of Force.

2. With the sample mounted, ensure the load bar round nut is slightly loose and not applying a force on the sample.

3. Click Record .
   NOTE: If the position and force data on the graph do not start at zero, check the sensor properties by opening the Hardware Setup tool and clicking the Properties icon next to the sensor’s name. Make sure the check box for Zero Sensor Measurements at Start is checked.

4. Slowly turn the crank clockwise until the force reading is approximately 100 N. Note the position and force data being plotted on the Graph display.

5. With data still being recorded, slowly turn the crank back counterclockwise, carefully watching the Digits display. Continue turning the crank until the force is between 10 and 20 N, then stop. Do NOT let the force go back to 0 N.

6. Turn the crank clockwise again to increase the force to the same level as before. Take note of how the second plot of data looks on the graph compared to the first.

7. If the second plot of data “tracks” on top of the first plot, then the sample is properly seated. If not, repeat the process of applying and unloading force until two consecutive plots of data track on top of each other. (This may take several repetitions.)

8. Return the crank to a position where 100 N of force are on the sample, then click Stop. Since the Materials Testing Machine is set to automatically zero itself the next time you begin recording data, this puts a pre-load of 100 N on the sample, improving data quality.

Applying a tension force

1. If you have not already done so, create a display in Capstone to measure your desired quantities, as described in Software setup.
2. Click Record to start collecting data.
3. Turn the crank in a clockwise direction to move the load bar upward and apply a tension force to the tensile sample. Observe the graph display of force and position.
4. When the sample breaks, or when the maximum force covered by the compliance calibration is reached, stop recording data.

Comprehensive Materials Testing System components
The following sections will outline the use of the various components which come with the Comprehensive Materials Testing System (ME-8244). Note that these products can also be individually ordered separately from the apparatus. For information on collecting data using these components, see the experiment library for the Comprehensive Materials Testing System at www.pasco.com/resources/labexperiments/collection/35.
Using the Bending Accessory
The Bending Accessory (ME-8237) includes a plunger, a base with two adjustable support anvils, a small hex key, and two mounting screws. The plunger can be mounted on the bottom of the load bar using the load bar round nut. The base for the adjustable anvils can be screwed onto the top of the load cell.

1. The spacing between the support anvils can be adjusted if desired. Use the hex key to loosen the screws holding the anvils, slide them to the desired distance from each other, and tighten the screws securely.
2. Insert the threaded rod attached to the plunger into the bottom of the hole in the load bar. Hold the plunger in place.
3. Use the round nut to secure the plunger in place on the load bar.
4. Remove the screws from the anvil base, then position the base on top of the load cell.
5. Align the threaded holes in the base with the threaded holes near the top of the load cell. Insert the screws into these holes and tighten them with the hex key to secure the base in place.
6. Place a sample for testing on the two support anvils.
7. Attach the two safety shields to the front and back of the load bar. Adjust the position of the shields if needed.
8. Turn the crank counterclockwise to lower the load bar and apply a force to the sample via the plunger.
   The setup of the Bending Accessory on the Materials Testing Machine is shown in Figure 6.

Using the Flat Coupon Fixture

The Flat Coupon Fixture (ME-8238) includes two coupon clamps and a “tee- handle” wrench with a 3/8″ socket. One of the clamps fits into the load cell, and the other fits into the load bar. These clamps can be used to mount a Stress Strain Apparatus Coupon, either plastic (AP-8222) or metal (AP-8223), onto the Materials Testing Machine for tensile strength measurements.

1. Loosen, but do not remove, the hex nut on each clamp. The jaws of the clamp are spring-loaded, so the moveable jaws will separate from the fixed jaws.

2. Screw the clamp with the shorter threaded section into the load cell.

3. Place the threaded section of the other clamp up through the hole in the load bar, then use the round nut to hold this upper clamp in place. Do NOT completely tighten the round nut yet.

4. Carefully place one end of a coupon between the jaws of the bottom clamp.

5. While holding the moveable jaw to keep it aligned with the fixed jaw, use the wrench and socket to tighten the hex nut.
   IMPORTANT: Each coupon is fragile. Do NOT let the moveable jaw twist out of alignment with the fixed jaw, as this might bend the coupon.

6. Rotate the upper clamp so that it is aligned with the lower clamp.

7. Adjust the position of the load bar until you have room to carefully place the free end of the coupon between the jaws of the upper clamp.

8. While keeping the moveable jaw aligned with the fixed jaw, tighten the upper clamp’s hex nut with the wrench and socket.

9. While holding the upper clamp so it remains parallel to the lower clamp, tighten the round nut slightly to remove any slack in the coupon.

10. Attach the two safety shields to the front and back of the load bar. Adjust the position of the shields if needed. With the coupon installed, you can now conduct tension experiments similar to those done with the tensile samples in previous sections.

Using the Shear Accessory

The Shear Accessory (ME-8239) consists of two pieces of hardened steel, a front piece and a back piece, held together by two permanent screws. A package of Shear Samples (ME-8240) and a pair of mounting screws are also included. The front piece can slide vertically relative to the back piece, which is designed to be mounted on the load cell using an included hex key. The two pieces have pairs of matching holes with four different diameters to fit a variety of test samples. The hole diameters, from top to bottom, are about 0.067 in (1.7 mm), 0.099 in (2.5 mm), 0.130 in (3.3 mm), and 0.161 in (4.1 mm). These holes are designed to accommodate rods with diameters of 1/16 in, 3/32 in, 1/8 in, and 5/32 in respectively. The Shear Samples include three 1/8 inch diameter rods each of aluminum, brass, and mild steel.
IMPORTANT: Do NOT use any samples with a hardness greater than mild steel!

1. Using the two mounting screws, attach the back piece of the Shear Accessory to the top of the load cell. Tighten the screws using the included hex key.

2. Raise the front piece by hand as far as it will go. When doing this, the holes in the front piece align with the matching holes in the back piece.

3. Insert the test sample through the pair of holes that best matches the diameter of the sample.
   TIP: Use a sample long enough to extend about a quarter inch (~6 mm) beyond the front and back pieces. This length makes it easier to remove the sample remnants from the accessory after the test while not obstructing the shields.

4. Adjust the position of the load bar so that it rests on the top surface of the front piece.

5. Attach the two safety shields to the front and back of the load bar. Adjust the position if needed.

6. When you are ready, turn the crank handle counterclockwise to move the load bar downward, applying a shearing force to the sample.

Using the Photoelasticity Accessory
The Photoelasticity Accessory (ME-8241) is designed to demonstrate the photoelastic phenomenon in clear plastic samples. Viewing these samples through crossed polarizers
reveals patterns of different colors, which show stress distribution in the sample. The Accessory includes two rectangles of polarizer material that can be attached to the Velcro® loop material on the Materials Testing Machine’s load bar, as shown below. For best results, place a light source so that it shines through the polarizers from behind.

The Photoelasticity Accessory also includes a set of
Photoelastic I-Beams (ME-7011), including 24 #3 beams and 24 #4 beams. These beams are similar to the I-Beams that are supplied in the Comprehensive Materials Structures System, as well as various PASCO Structures Systems, such as the Truss Set (ME-6990). However, the Photoelastic I-Beams are made of a clear polycarbonate plastic and do not have holes in the web area of the beam. These beams can be mounted on the Materials Testing Machine using the Structures Beam Adapter (ME-8242). When viewed through the polarizers, the distribution of stress in these beams can be beams can be studied. The #3 I-Beam is 11.5 cm long, and the #4 I-Beam is 17 cm long.
Using the Structures Beam Adapter
PASCO offers a variety of beams that can be used with the Materials Testing Machine. These beams include models of Ibeams and other structure elements. The Structures Beam Adapter (ME-8242) is designed to hold a structures beam so it can be tested under tension and compression. The Structures Beam Adapter consists of two clamps and   hex key. Each clamp has two jaws, one of which can be removed so that one end of a structures beam can be put in the clamp. The threaded ends of the clamps fit into the load bar and load cell of the Materials Testing Machine.

1. Using the included hex key, remove the screws that hold the two parts of each clamp together.
2. Put one end of a structures beam, such as a #3 I-Beam, into one half of the load bar clamp, which has the longer threaded section.
3. Use the screws to reattach the other part of the load bar clamp.
4. Repeat Steps 2 and 3 to attach the load cell clamp, which has the shorter threaded section, to the other end of the beam.
5. Screw the threaded end of the load cell clamp into the hole in the top of the load cell.
6. Using the crank handle, lower the load bar until the threaded end of the load bar clamp extends through the hole in the load bar.
7. Use the round nut to secure the load bar clamp in place.
8. Attach the two safety shields to the front and back of the load bar. Adjust their position if necessary.
   The mounted structures beam can now be subjected to compression or tension forces.

Using the Clevis Grip
The Clevis Grip (ME-8245) is designed to allow tensile testing of samples which have hooked ends or through holes. Each grip includes a pin which can be inserted into a hole in the grip, securing the sample in place. The diameter of each clevis pin is 0.187 in (0.47 cm). Each pin contains a pair of small, springloaded spheres near its end, which
keep the pin from slipping out of the clip.
The grip with the longer threaded section is designed to be mounted in the load bar of the Materials Testing Machine and secured in place with the round nut. The grip with the smaller threaded section and hex nut is designed to be mounted in the load cell. (See Figure 8.)
NOTE: As with all other tests, remember to use the safety shields when performing experiments!

Using the 10-32 Adapter

Several devices used to hold materials in place during material testing have a 10-32 hole designed for mounting devices on a materials tester. The 10-32 Adapter (ME-8238) is designed to connect these devices to the load bar and load cell of the Materials Testing Machine.
The 10-32 Adapter includes two components, as shown below.
The adapter with the longer larger-diameter threaded section is designed to be mounted in the load bar of the Materials Testing Machine. The adapter with the shorter larger-diameter threaded section and hex nut is designed to be mounted in the top of the load cell.

Using the Compression Accessory
The Compression Accessory (ME-8247) is designed to work with the Materials Testing Machine to compress samples. The accessory consists of two one inch (2.54 cm) diameter platforms that provide a sturdy base for compression samples. The platform with the shorter threaded end should be mounted into the load cell, and the platform with the longer threaded end should be mounted into the load bar and secured in place with the round nut.

The Compression Accessory also includes twenty Compression Samples (ME-8248). These polyethylene cylinders are approximately 0.5 in (1.3 cm) in diameter and 0.75 in (2 cm) in length.
NOTE: As with all other tests, remember to use the safety shields when performing experiments!
Using the Four-Point Load Anvil
The Four-Point Load Anvil (ME-8249) extends the capabilities of the Bending Accessory. When used with the Bending Accessory and the Materials Testing Machine, data to find the tested sample’s flexural plastic modulus and modulus of rupture can be measured, recorded, and analyzed.

To use the accessory, simply replace the plunger from the Bending Accessory with the Four-Point Load Anvil and follow the instructions as normal.
Using the Cast Beam Spares Set
The Cast Beam Spares Set (ME-6983) includes 30 “Rebar” members and 10 “molds”. A Cast Beam consists of a beam that is a model of the reinforcement bars (“rebar”) used in construction and a mold that is used to produce a model of a beam of reinforced or prestressed “concrete”. A mixture of fine sand, plaster, and water is poured into the assembled rebar beam and mold. After the mixture hardens and the mold is removed, the beam can be used as a #4 beam in any PASCO Structure Set or tested on the Materials Testing Machine.

Figure 9 shows a Cast Beam being used with the Materials Testing System, Bending Accessory, and Four-Point Load Anvil.

Using the Thin I-Beams

The Thin I-Beams set (ME-7012) consists of 48 thin I-Beams, including 24 each of two sizes: #3 beams and #4 beams. These beams are like those found in PASCO Structures Systems, but with no holes in the web area. Therefore, when used with the Materials Testing Machine, the test results are more like those that would be obtained for the types of metal I-Beam used in construction.

Maintenance

This equipment requires minimal regular maintenance. The leadscrews need to be kept clean and may need to be relubricated at some point. Use a food grade anti-seize grease containing PTFE (polytetrafluoroethylene, commonly known as Teflon®) to lubricate the leadscrews.
