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.

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.
