Introduction
The PASCO AP-8214A Stress/Strain Apparatus illustrates the relationship between stress and strain for various mate-
rials. The apparatus stretches a test coupon (and breaks it in some cases) while measuring the amount of stretch and
force experienced by the test coupon. Data acquisition software can be used to generate a plot of force versus dis-
placement and also a plot of stress versus strain.
The Stress/Strain Apparatus requires a ScienceWorkshop or PASPORT interface, DataStudio software, a Rotary
Motion Sensor (RMS), and a Force Sensor. Included with the apparatus are four types of metal test coupons and four
types of plastic test coupons. Also included are a tee handle with a socket that fits the hex nuts on the coupon clamps,
a bar for calibrating the apparatus, and spare hex nuts for the coupon clamps.
This manual includes instructions for setting up the Stress/Strain Apparatus with ScienceWorkshop or PASPORT sen-
sors. It also describes how to do the calibration and the data collection using the DataStudio set-up files that are on the
included PASCO Experiment Setup CD-ROM. The CD-ROM has a folder labeled “AP-8214 SETUP” that contains
two DataStudio configuration (set-up) files, two DataStudio workbook files, and a sample data file.

The two sensors used on the Apparatus require a single multi-port interface such as the Xplorer GLX (PS-2002) or PowerLink
(PS-2001), or two single-port interfaces such as the USB Link (PS-2100) or Xplorer (PS-2000).
