- A 63.0 kg bungee jumper jumps off a bridge and undergoes damped simple harmonic motion. If the amplitude of oscillation reduces to 0.3679 of the initial amplitude in 0.773 s, what is the damping coefficient?The suspension system of a 2200 kg car is made of springs that are compresses by 8 cm when the mass of the car is placed on it. Also, the collision amplitude decreases by 50% each cycle. Find the damping constant 6 (in units of kg/s) for the spring and shock absorber system of one wheel, assuming each wheel supports 550 kg. 134The motion of a rail car is recorded and found to have an overall grms level of 0.23 Grms. This data is used to reproduce the motion in the lab on a random vibration table. What grms level would the PSD profile need to be scaled to for simulation of a 10 hour train ride in 3 hours in the lab?
