Advanced Solids MixedHardQuestion 6394

Question

A wire stretches by x₀ under load W. If load is 4W and length is halved (same material, same area), extension:
  1. A
    x₀
  2. B
    2x₀
    Correct
  3. C
    4x₀
  4. D
    x₀/2

Correct answer

2x₀

Explanation

ΔL = FL/AY. New: F=4W, L=L/2. New ΔL = 4W×(L/2)/AY = 2WL/AY = 2×(WL/AY) = 2x₀.
