A shaft design application for a conveyor belt system requires a mean time between service of 15000 hours, a desired reliability of 95% with an application factor determined to be 1.25, determine the required bearing catalogue rating if the design load is 375 lbs at 1800rpm. Assume the manufacture life rating is 90*10^6 with xo=0.02, θ=4.48 and b=1.49.

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.
