Detemine the internal forces in the wires supporting the hanging beam shown below. Assume all elements are pin connected at their ends and that the wires are in extensible or axially 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
