A 120-kg machine is placed at the midspan of a 85-cm aluminum (E = 100 x 10°) N/m² simply. supported beam (I=4.56 x 10 m). When the machine, which has a rotating unbalance of 0.68 kg-m, operates at 458 rad/s, its steady-state amplitude is measured as 13.2 mm. If the damping is assumed to be hysteretic, determine the beam's hysteretic damping coefficient.

A 7-kg block is suspended by three identical springs, each with k = 200 N/m. The bottom of the block is attached to a dashpot that provides a damping force of F= 50|M N, where v is in m/s. At t = 0 s, the block is given an initial velocity upward of 0.6 m/s from its equilibrium position. (a) What is the natural frequency of the system? (b) Show whether this is an underdamped, a critically damped, or an overdamped system. (c) What is the frequency of the damped system? (d) What is the amplitude of the damped oscillation?
