This compact Stress/Strain Apparatus shows the stress and strain during the entire process of stretching and breaking a material. PASCO has scaled-down the typically expensive engineering devices so that this apparatus is able to do all the physics without the high cost of a materials testing machine.

Since the Stress/Strain Apparatus shows the entire stress versus strain curve, it is possible to measure a wide range of material properties including Young’s Modulus, the yield strength, tensile strength, ductility and toughness of the material. In addition, the different curve shapes for different materials can be compared.

DataStudio software allows students to determine Young’s Modulus by measuring the slope of the initial straight line (the elastic region) and to determine the toughness by integrating under the curve.
