The uniform slender bar ABC weighs 4.3 lb and is initially at rest with end A bearing against the stop in the horizontal guide. When a constant couple M = 62.1 lb-in. is applied to end C, the bar rotates causing end A to strike the side of the vertical guide with a velocity of 11.6 ft/sec. Calculate the loss of energy ΔE (enter a positive number) due to friction in the guides and rollers. The mass of the rollers may be neglected.

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.
