A machine with a rotating shaft has a total weight of 200 lbs, and is supported by springs. The damping constant for the system is found to be 3 lb.sec/in. The resonant speed is determined exprimentally to be 1200 rpm, and the corresponding amplitude of the main mass of the machine is 0.50 inches. (a) Determine the amplitude for a speed of 2400 rpm. (b) Determine the fixed value which amplitude will eventually approach at high speed. (c) Determine the maximum dynamic force, F_tau, transmitted to the foundation at the resonant speed.

A block of weight 12 lbs is placed on a cart of weight 40 lbs that is attached to a spring with a constant of 500 lb/in. The coefficient of static friction between block A and cart B is 0.15, and the coefficient of friction between cart B and the ground is negligible. a.) Find the maximum amplitude of oscillation of the system to prevent block A from sliding. b.) Use conservation of energy to determine the maximum velocity and...

A rotating shaft has four masses A, B, C, and D attached to it. The planes that these masses rotating at are spaced equally. The magnitude of the masses are 6.5, 11.8, 4.2, and 5.1 kg, respectively. Calculate the radii that the masses should be placed at from the center of the shaft such that the system be in a complete dynamic balance. The shaft angular speed varies between 1760 and 1875 r.p.m. Assume whatever dimension or quantity that you...
