Included Equipment

The 

Materials Testing Machine

 (ME-8236) includes a cali-

bration rod and nut, a load bar round nut, and a pair of safety 
shields with Velcro® hook material.

Calibration Rod and Nut, Load Bar Round Nut, 
Safety Shields

The calibration rod and nut can be used to determine 
how much the Machine itself flexes as force is applied, 
either in tension or in compression. 

The load bar round nut is used to connect one end of a 
tensile sample to the load bar, for example, or can be 
used to attach an accessory or adapter to the bottom side 
of the load bar. 

The safety shields attach to the Velcro® loop material 
on the front and back of the load bar.

Materials Testing System

The 

Materials Testing System

 (ME-8230) consists of the 

Materials Testing Machine, plus a PASPORT interface called 
the USB Link, PASCO Capstone Software, and sixty tensile 
samples. 

The USB Link connects the sensor cable of the Materials 
Testing Machine to a USB port on a computer. The PASCO 
Capstone software records, displays, and analyzes the data 
from the Materials Testing Machine. (The software is avail-
able as an automatic digital download from PASCO.) 

The tensile samples include four metals: aluminum, brass, 
annealed steel, and steel and two plastics: acrylic and poly-
ethylene, for tensile strength testing. There are ten samples 
for each material.

Tensile Sample Information

All the tensile samples (ME-8231 through ME-8235 and 
ME-8243) have an overall length of 90 millimeters (mm) or 
3.5 inches. The center section of each sample has an approx-
imate diameter of 3.3 mm or 0.131 inches. The threaded 
ends are metric M12 x 1.75.

The tensile samples can be ordered separately. 

The table shows typical values. 

Accessories

Table 2 lists accessories and adapters that are included in the 
Comprehensive Materials Testing System and are available 
separately for the Material Testing Machine. 

Other accessories and adapters are being developed. 

Replacement Items

Also available separately are replacement items such as the 
previously mentioned Tensile Samples, the Materials Shear 
Samples (ME-8240) with nine metal rods (three each of alu-
minum, brass, and steel), the Plastic Coupons (AP-8222) 
with ten samples each of four different plastics, the Metal 
Coupons (AP-8223) with ten samples each of five different 
metals, and the MTS Compression Samples (ME-8248).

About This Manual

The manual describes the basic setup of the Materials Test-
ing Machine and the accessories and replacement items 
included in the Comprehensive Materials Testing System. It 
also describes the procedure for calibrating the Materials 
Testing Machine using the included calibration rod and nut.

Experiment Guide

Operation

Caution: Be sure to wear adequate eye protection 
when using the Materials Testing Machine or its 
accessories. Operate the Machine from behind a 
protective shield.

Basic operation involves mounting the Materials Testing 
Machine firmly to a sturdy support, calibrating the Machine, 
mounting the item to be tested onto the Materials Testing 
Machine, connecting the Materials Testing Machine to an 

diameter = 3.3 mm
