Question

A material has Poisson's ratio 0.5. If a uniform rod of it suffers a longitudinal strain of 3×10^-3 , what will be percentage increase in volume?
(1) 2% (2)3% (3)5% (4)0%

Answer 1

Here, E = 3k(1 - 2μ) where, E = Modulus of elasticity μ = Poisson's ratio k = Modulus of elasticityHere, μ = 0.5 then k⟶∞ k = ΔP (ΔVV) If k⟶∞ ...
