Class 11 Physics Mechanical Properties of Solids Introduction

Introduction

  • This lesson is focussed on how we stretch, compress and bend a body.
  • We have seen that if we stretch a rubber and let it go it deforms but by applying the force, it again regains its original shape.
  • If we take an aluminium rod and apply very strong external force on it, the shape of the rod might change but it does not regain its original position.
  • We will take a look why some materials are elastic and why some are plastic.
