Materials Testing Machine

Operation

ture of tested samples can be measured, recorded, and ana-
lyzed. 

The Cast Beam Spares Kit 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 construc-
tion, and a mold that is used to produce a model of a beam of 
reinforced “concrete” 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.

The illustration shows a Cast Beam with the Materials Test-
ing Machine and the Four-point Load Anvil attached to the 
Bending Accessory.

The Photoelastic I-Beams are similar to the #3 I-Beams and 
#4 I-Beams that are part of the PASCO Structures Systems 
(such as the Truss Set, ME-6990). However, the Photoelastic 
I-Beams differ in that they are clear polycarbonate plastic 
and do not have any holes in the web area of the beam. They 
can be mounted on the Materials Testing Machine using the 
Materials Structures Beam Adapter. When viewed with the 
Materials Photoelasticity Accessory, the distribution of stress 
in the beams can be studied. 

The set includes twenty-four each of the two sizes of 
I-beams. The #3 I-Beam is 11.5 cm long, and the #4 I-Beam 
is 17 cm long.

The Thin I-Beams set consists of 48 thin I-Beams of two 
sizes: #3 Beam (24) and #4 Beam (24). The beams are like 
those in the PASCO Structures Systems, but there are no 
holes in the web area. Therefore, when used with the Materi-
als Testing Machine, the test results are more like the results 
would be for the type of metal I-Beam used in construction.

Regular maintenance for this equipment is minimal. The 
leadscrews need to be kept clean, and they may need to be 
re-lubricated at some point. Use a food grade anti-seize 
grease containing PTFE (polytetrafluoroethylene, commonly 
known as Teflon®).

If problems arise with the Materials Testing Machine, notify 
PASCO scientific. It is not recommended that you attempt to 
fix this equipment yourself. (See the Technical Support 
information at the end of this manual.) 

NOTE: An Experiment Guide in electronic format is avail-
able to download from www.pasco.com. The Experiment 
Guide includes information about the calibration procedure 
and also describes the available Capstone Workbook files for 
the Materials Testing Machine.

Enter “Materials Testing System” in the Search window and 
look for the downloadable file(s) under “User Resources”. 

The list of Capstone Workbook files for the Materials Test-
ing Machine includes the following. Each lab is available as
