Q1.What is the nature of the deformation in a body under hydraulic compression?

  • AChange in shape without change in volume
  • BChange in volume without change in geometrical shape
  • CChange in both shape and volume
  • DNo deformation at all

Q2.Which material is more elastic: steel or rubber?

  • ARubber, because it stretches more
  • BSteel, because it has a larger Young's modulus
  • CBoth are equally elastic
  • DNeither is elastic

Q3.Longitudinal strain is defined as:

  • Achange in length / original length
