Abstract

In this article we present a simple technique for determination of the Young modulus of the material of a metallic ruler using it as a cantilever. This method employs with a slide potentiometer and a digital multimeter. The linear region of potentiometer resistance which is calibrated in terms of length has been used to record the load vs. resistance data. The value of the Young modulus determined from the linear least square fit to the load-resistance data and its value found comparable with the accepted value.
