Question

Let a wire be suspended from the ceiling (rigid support) and stretched by a weight W attached at its free end. The longitudinal stress at any point of cross-sectional area A of the wire is:, Zero, 2 W A, W A, W 2 A

MARKS App · Accepted Answer

Longitudinal stress is given by, s t r e s s = f o r c e a r e a = W A In case of ideal wire, stress at each point will be the same and will be equal to W A .
