Abstract In this experiment, a simply supported beam is used and the variations of deflection of a simply supported beam with load, beam thickness and material are investigated. It is found that the deflection of the beam changes linearly with the load and as the beam thickness increases, the beam deflection decreases. In addition, since […]
