Materials Testing Machine

Operation

Lower the load bar so that the longer threaded section of the 
sample goes up through the hole in the center of the load bar. 
Adjust the load bar until the bottom edge of the longer 
threaded section is flush with the bottom of the load bar. 
While holding the tensile sample so it does not turn, screw 
the sample nut onto the longer threaded section until the 
sample is held tightly in place.

Attach the Velcro® hook material on the two safety shields 
to the Velcro® loop material on the front and back of the 
Load Bar. Adjust the position of the shields so that they will 
block any fragments that may come from the sample. 

Prepare PASCO Capstone software to record data. (If there is 
a stored calibration file that is to be used, select it in the 
“Calibration” window.)

Start data recording. Turn the crank in a clockwise direction 
to apply a tension force to the tensile sample. Observe the 
graph display of force and position. (Note that the default for 
the Materials Testing Machine in the software shows force 
and position as ‘negative’ when a tension force is applied. 
See Appendix A for information about changing signs.))

When the sample breaks, or is stretched the maximum 
amount, stop data recording. 

The Materials Bending Accessory includes a plunger, a 
adjustable support anvils, and a small hex key (allen 
wrench). The plunger is mounted on the bottom of the load 

bar using the sample nut. The base for the adjustable anvils 
is screwed onto the top of the load cell. 

The spacing between the two triangular support anvils can be 
adjusted. Use the hex key to loosen the screws holding the 
anvils and slide them closer together or farther apart. Tighten 
the screws securely.

Use the sample nut to secure the plunger in place on the load 
bar. Remove the screws from the base for the anvils and 
align the base on top of the load cell. Use the screws and the 
hex key to fasten the base in place.

Place a sample for testing on the two support anvils. 

Attach the Velcro® hook material on the two safety shields 
to the Velcro® loop material on the front and back of the 
Load Bar and adjust the position of the shields if needed.

Turn the crank counterclockwise to apply a compression 
force through the plunger onto the sample. 

The Materials Coupon Adapter includes two coupon clamps, 
a “tee-handle”, and a 3/8” socket (12 point). One clamp fits 
in the load cell and the other fits in the load bar. They can be 
used to mount a plastic coupon (AP-8222) or metal coupon 
(AP-8223) onto the Materials Testing Machine for testing of 
tensile strength.
