INTRODUCTION:

 

  • The relative elongation of a material when subjected to tension.
  • Tensile Strain is nothing but deformation (change in length) of the body or material due to load.
  • Therefore tensile strain is change in length to the original length. It may be length or volume.

PROBLEM:

 

A metal bar which is a part of frame is 50 mm diameter and 300 mm long. It has a tensile force acting on it the modulus of elasticity is 205 G Pa.
Calculate the stress and strain in the bar and the amount it stretches?
