Transcribed Image Text:Objective
To determine the deflection in a simply supported beam using the bending bar apparatus.
Introduction
Horizontal loading, perpendicular to the longitudinal axis causes bending deformation or
deflection. The loading can be categorized as point central load, uniformly distributed load, or
uniformly varying load. In a simply supported beam, the two supports react in the longitudinal
and transverse directions.

Theory
Bending Moment
A bending moment is the reaction induced in a structural element when an extemal force or
moment is applied to the element causing the element to bend.
Deflection
Measure of deformation due to transverse loading is called deflection or vertical
deformation from initial point due to external load is called deflection. It is denoted by ô.
