Elastic Properties of Solid

Performance Objectives

Students should be able to:

  1. State Hook’s law, Young Modulus law
  2. Determine the work done in springs and elastic string

Content

Elasticity is the ability of a material to regain its original shape or size after deformation or after removal of stress/force,   or after it has been compressed. Deformation occurs when a wire is stretched or compressed. Deformation is elastic if the wire returns to its original position, while it is plastic if it does not return to its original position.

Terms used in Elasticity

  1. Elastic limit: Elastic limit is the maximum load (force) which a body can experience and still retain its original size/shape once the load/force has been removed. It can also be defined as the point on a stress/strain or load/extension graph beyond which Hooke’s law is no longer obeyed.
  2. Yield.... View More
