Yet another thermodynamic identity
Prove the following thermodynamic derivative and determine what should replace the question marks. Note that you do not have to reduce this to the standard expressions, but can leave it in terms of partial derivatives
The cross-section of a turbine rotor disc is designed for uniform strength under rotational conditions. The disc is keyed to a 60 mm diameter shaft at which point its thickness is a maximum, what is the required maximum thickness
The figure shows an N-truss girder, loaded by concentrated vertical forces of magnitude 3P at the joints F and J, and of magnitude 6P at the joints G, H and I. All bars are elastic with stiffness EA.
1 kg of a gas in a piston-cylinder assembly undergoes a Carnot power cycle for which the isothermal expansion occurs at 800 K. The change in specific entropy of the gas during the isothermal compression, which occurs at 400 K is -25 kJ/kg. K.
