a thin rod of A thin rod of negligible mass and are of cross-section 4x10^–6 m2, suspended vertically from one end, has a length of 0.5 m at 100°C. The rod is cooled to 0°C, but prevented from contracting by attaching a mass at the lower end. (Given Y = 10^11 Nm–2 the co-efficient of linear expansion α = 10^–5 K–1 and the value of g is 10 ms–2). Then mass attached and energy stored in the rod are
