An accelerometer has a damping ratio of 0.5 and a natural frequency of 18,000 hz. it is used to sense the relative displacement of a beam to which it is attached. if an impact to the beam imparts a vibration at 4500 hz, (a) estimate the dynamic error and phase shift in the accelerometer output. (b) estimate its resonance frequency.

What are the two (02) benefits, which may result from a successful implementation of preventive maintenance (pm) program in an organization? (clo3)a)- lean manufacturing b)-overlapping responsibilities c)-the planner is not qualified d)-accurate contractor information e)-reduction in equipment redundancies f)-accurate stores information
