Two identical cylinders with a movable piston contain 0.7 mol of helium gas at a temperature of 300 k. the temperature of the gas in the first cylinder is increased to 472 k at constant volume by doing work w1 and transferring energy q1 by heat. the temperature of the gas in the second cylinder is increased to 472 k at constant pressure by doing work w2 while transferring energy q2 by heat. find δeint, 1, q1, and wi for the process at constant volume.

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.
