Determine the components of the reactions at a and e when a counterclockwise couple of magnitude 120 n * m is applied to the frame a.) at b, b.) at d.

The characteristic roots of a dynamic system are: 1.7920 1.8160 i, -1.7920 1.8160 i, -0.4160 what is the order of this system? what are the settling time and damping ratio of the system?

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

When subject to a steady load (within elastic range) over a long period of time, what is the major difference in material behavoir between steel and plastic?
