Question

The young's modulus of a perfectly rigid body is what?

Answer 1

Answer:YOUNG'S MODULUS OF A PERFECTLY RIGID BODY. Answer: Young's Modulus = Stress/Strain, Since a perfectly rigid body won't yield any strain, irrespective of amount of stress, it's Young's modulus is infinite.

Answer 2

Answer:

A perfectly rigid body means no matter how much load you apply it is neither going to deform nor any shape change. The high school kinematics and dynamics we study inherently assumes that body is perfectly rigid and no amount of force is going to change its shape.
