Q1A wire of length 2 m and area 1 mm² stretches by 1 mm under a load of 10 N. Young's modulus is:Q2Two wires of same material have lengths L and 2L and radii r and 2r. The ratio of their elongations under the same force is:Q3Bulk modulus is defined for:Q4Poisson's ratio is the ratio of:Q5The energy stored per unit volume in a strained wire is:Q6A copper and a steel wire of same length and diameter are stretched by the same force. Which has greater elongation?

Q1A wire of length L and cross-section A is stretched by an amount x. If it is further stretched by dx, the work done is:Q2A rod of length L, Young's modulus Y, and area A is fixed at both ends and heated by ΔT. The thermal stress developed is (α = coefficient of linear expansion):Q3For an incompressible material, Poisson's ratio is:Q4The relation between Y (Young's), B (Bulk), and η (Shear) moduli is:Q5If a uniform rod under its own weight is hung vertically, the total elongation is:
