Deflections of Beams
in this chapter, we describe methods for determining the equation of the
deflection curve of beams and finding deflection and slope at specific points
along the axis of the beam

Mechanical Properties of Metals
Many materials (when in service) are subjected to forces or loads(Al. alloy:airplane wings; steel:
automobile axle). In such situation need to know mechanical properties of materfial so to design

4.1 The Concept of Stress An Introduction
We have talked about internal forces, distributed them uniformly over an area and they
became a normal stress acting perpendicular to some internal surface, or a shear stres

EXPERIMENT TITLE: Poisson's Ratio -Flexure
The purpose of this experiment is to measure the Poisson's Ratio of an aluminum
beam by loading the beam in cantilever bending and using axially and transversely
bonded strain gages.
