Ahorizontal cylinder is separated into two compartments by an adiabatic frictionless piston. one side contains 0.2 m3 of nitrogen and the other side contains 0.1 kg of helium, both initially at 20°c and 95 kpa. the sides of the cylinder and the helium end are insulated. now heat is added to the nitrogen side from a reservoir at 500°c until the pressure of the helium rises to 120 kpa.

determine

(a) the final temperature of the helium,

(b) the final volume of the nitrogen,

(c) the heat transferred to the nitrogen,

(d) the entropy generation during this process.

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.
