Question

calculate tensile strain when a force of 3.2 KN to applied to a bar of original length 2.8M extend the bar by 0.5mm​

Answer 1

Tensile stress=F⊥A. tensile strain=ΔLL0. Compressive stress and strain are defined by the same formulas, Equation 12.34 and Equation 12.35, respectively. The temperature is a measure of stress, the physical force being applied to the surface of a material . Initial length of wire = L, Final length = 2L, Hence extension of wire = l = 2L – L = L, Area of cross-section = 1 cm² = 1 × 10-4 m², Young's modulus of elasticity = Y = 2× 1011 N/m². To Find: Stretching force = F =.
