A bar 3 cm in diameter was subjected to tensile load 54 kN and the measured extension on 30 cm length was 0.112 mm and change in diameter was 0.00366 mm . Calculate Poisson's ratio and the value of three modulus.

Explanation

Poisson's ratio is calculated using the formula ν = -Δd / Δl, where Δd is the change in diameter and Δl is the change in length. Young's modulus and modulus of rigidity are calculated using the formulas E = σ / (Δl / l) and G = E / (2(1 + ν)).
