An iron rod of length 2 m and cross-sectional area of 50 mm^(2) is stretched by 0.5 mm, when a mass of 250 Kg is hung from its lower end. Young's modulus of iron rod is

Calculate the work done in stretching a steel wire of length 2m and cross sectional area 0.0225mm2 when a load of 100 N is slowly applied to its free end.(Young's modulus of steel = 2 x 10¹¹ N/m² )

When a wire 2 m long and 0.05 cm^(2) in cross-section is stretched by a mass of 2 kg, it increases in length by 0.04 mm. Young's modulus of the material of the wire is (g=10ms^(-2))
