Find the ratio of strain energies stored in bars A and B of the same axial tensile loads. The bar A is of 50mm diameter through out its length, while bar B though of same length as of A but has diameter of 25 mm for the middle one - third of its length and the remainder is of 50 mm . Assume gradual load

Heat is allowed to flow out of an ideal gas at constant volume so that it's pressure drops from 2.2atm to 1.4atm. Then the gas is expanded at constant pressure from a volume 6.8L to 9.3L until the temperature reaches it's final value.what is the total work done by the gas in the process,the internal energy of the gas and the total flow of heat into or out of the gas.

The steam is heated to raise its temperature to 150°C. Show the process on a sketch of the p–v diagram, and evaluate the pressure, increase in enthalpy, increase in internal energy, increase in entropy of steam, and the heat transfer. Evaluate also the pressure at which the steam becomes dry saturated.

In an automobile engine, the gas (a mixture of air and petrol) in the cylinders is compressed to 1\9 of its original volume. The initial pressure is 1.0 atm and the initial temperature is 27 °C.
If the pressure after compression is 21 atm, the temperature of the compressed gas is (Assume that the gas behaves as ideal.)
