bending moment is simply defined as “the algebraic sum of the moments of all the forces which induces bending of an element” (1). The aim of this assignment is to work out the bending moment in a simplysupportedbeam when different concentrated loads are applied to it. A simplysupportedbeam is a structure...

Bending Moments are rotational forces within the beam that cause bending. At any point within a beam, the Bending Moment is the sum of: each external force multiplied by the distance that is perpendicular to the direction of the...

3.3 Analysis for gravity loads
Simple framing If a simple framing is used, the analysis is quite simple because they can be considered as simplysupported. In such cases, shears and moments can be determined by statics. The gravity loads applied to the columns are relatively easy to estimate, but...

Diagrams for Beams
In addition to axially loaded bars/rods (e.g. truss) and torsional shafts, the structural members may
experience some loads perpendicular to the axis of the beam and will case only shear and bending

Experiment 7: Deflection of beams (Effect of beam length and width)
1. OBJECTIVE
The objective of this laboratory experiment is to find the relationship between the deflection (y) at the centre of a simplysupportedbeam and the span, width.

In this experiment we come to know how different amalgamation of loads and distances causes the variation of bending moments across the length of a beam. Another attribute of this report is that it envisage about the agreement of theoretical values calculated with those which are calculate during the...
