PhysicsNEET 2023Stress, strain and Hooke's law

Mechanical Properties of Solids

Let a wire be suspended from the ceiling (rigid support) and stretched by a weight WW attached at its free end. The longitudinal stress at any point of cross-sectional area AA of the wire is:

  1. A.2W/A2W/A
  2. B.W/AW/A✓
  3. C.W/2AW/2A
  4. D.Zero

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
