Class 11 Physics Mechanical Properties of Solids Hydraulic Stress

Hydraulic Stress

  • Hydraulic stress is the restoring force per unit area when force is applied by a fluid on the body.
  • For example:-
  1. Consider a rubber ball and if it is dipped in the pond .Due to the pressure of water from all directions force acts on the ball as a result, the ball seems to be slightly contracted.
  2. Because of the force exerted by the water there is restoring force which develops in the ball which is equal in magnitude to the force applied by the water but in opposite direction.
  3. This type of stress is known as hydraulic stress.
