Bar AB has a cross-sectional area A = 100 mm2 and modulus of elasticity E = 102 GPa. The distance H = 400 mm. If a 200 kN downward force is applied to bar CD at D, through what angle (in degrees) does bar CD rotate? Because the deformations are small, you can assume that the point B displaces downward vertically. (Bar AB is deformable, and bar CD is rigid.)

Water vapor initially at 10 bar and 400 °c is contained within a piston-cylinder assembly. the water lost heat to the surrounding according to isochoric (iso-volumetric) process until its temperature is 150 °c. the water is then condensed isothermally to saturated liquid. for the water as a system, calculate the work in kj/kg
