Suppose a steel strut having a cross-sectional area 4.00 × 10-4 m² and length 2.30 m is bolted between two rigid bulkheads in the engine room of a submarine. Assume the density of steel is the same as that of iron (7.86 x 103 kg/m³). (a) Calculate the change in temperature of the strut if it absorbs an energy of 3.00 × 105 J of thermal energy. °C (b) Calculate the compressional stress in the strut. Pa
