Materials Testing Machine

Operation

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

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 if needed. 

Clear plastic samples that are viewed through crossed polar-
izers reveal patterns of different colors that show stress dis-
tribution. The Materials Photoelasticity Accessory is 
designed to demonstrate the photoelastic phenomenon in 
clear plastic samples.

The Accessory consists of two rectangles of polarizer mate-
rial that can be attached to the Velcro® loop material on the 
Load Bar of the Materials Testing Machine.

To place the polarizers on the Load Bar, align a polarizer 
with the strips of loop material on the front of the Load Bar 
and press the edges of the polarizer so that the hook material 
adheres to the loop material. Repeat the process with the sec-
ond polarizer on the other side of the load bar.

Place a light source so that it shines through the polarizers 
from behind.

The PASCO Structures System includes a variety of beams 
that can be used with the Materials Testing Machine. The 
beams are models of I-beams and other structure elements. 
The Materials Structure Beam Adapter is designed to hold a 
structures beam so that it can be tested under tension and 
compression. 

The Materials Structures Beam Adapter consists of two 
clamps and an included hex key. Each clamp has two jaws, 
one of which can be removed so that an end of a structures 
beam can be put in the clamp. The threaded ends of the two 
clamps fit in the load bar and load cell of the Materials Test-
ing Machine. 

Use the included hex key to remove the screws that hold the 
two parts of the clamp together. Put the ends of a structures 
beam, such as a #3 I-Beam, into one part of each clamp, and 
then use the screws to reattach the other part of each clamp.
