ABSTRACT

In the vibrating beam experiment, an aluminum cantilever beam was made to vibrate. An accelerometer transducer was used to convert the mechanical vibrations into a signal that was fed into an oscilloscope via a power supply. The oscilloscope mapped the signal into a sine curve and displayed it on the screen. The oscillations’ decay curve was studied and the beam’s damping ratio was determined. The decay curve’s logarithmic decrement was used to determine the beam’s damping ratio and its natural frequency. The beam’s damping ratio was observed to be underdamped at a damping ratio of 0.0066.

Abstract

This experiment aims at determining the Young’s Modulus (E) by using the strain gauge technique. It is determined for a simply supported beam by measuring the strain in the beam when it is loaded in 3 point bending. i.e. load is applied exactly at the center of the beam. The bending of a beam is an example of Hooke’s Law, which states that, when an elastic body is strained in any way, the deformation is directly proportional to the applied stress provided the body is not strained beyond its elastic limit. In this experiment, Young’s Modulus is studied ...
