Strain Gauge Trainer
Model Number: SM1009
Bench-mounted system for teaching strain measurement in bending, torsion and tension.
Overview
Bench mounted bending system to test tension, torsion and bending to illustrate how resistance strain gauges work and methods of measuring strains in different structures. Can be used to demonstrate Young’s modulus and Poisson’s ratio.
The compact Strain Gauge Trainer fits on a bench or desktop. It contains everything needed to show students how resistance strain gauges work on three different structures. It is ideal for groups of two or more students to do experiments and for classroom demonstrations.
Students use the small set of masses to load the bending and torsion systems, and the large set of masses to load the tension system. They use theory and known dimensions to calculate the stresses and strains and compare them with the strains measured by the strain gauges. Students can also connect and compare the performance of quarter, half and full-bridge strain gauge connections for each structure.
