At a steady state, a thermodynamic cycle operating between hot and cold reservoirs at 1000K ands respectively. The cycle receives energy by heat transfer from the hot reservoir at a rate of 1500kW, and discharges energy by heat transfer to the cold reservoir. The cycle develops power at a rate of (a)0 (b) 250 kW and ()1000kW For each case, based on the Clausius inequality, determine whether the cycle operates reversibly, irreversibly or is impossible.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
