Abstract

A popular way to measure elastic modulus in Physics classes is to stretch a fine wire using known weights [1, 2]. Students divide the applied tensile stress by the measured tensile strain to obtain the elastic modulus. When engineering technology students take Statics and Strength of Materials courses, they learn how to apply basic physics concepts to mechanical structures, such as beams loaded in bending. This paper describes a simpler, less expensive approach for measuring elastic modulus, using the center-span deflection of a simply-supported beam. The method appeals to Strength of Materials students because it uses concepts learned in their coursework, and students respond positively to hands-on demonstrations.
