Chapter 13, Problem 13.2P
A quarter-car representation of a certain car has a stiffness k = 2000 lb/ft. which is the series combination of the tire stiffness and suspension stiffness, and a damping constant of c = 360 Ib-sec/ft. The car weighs 2000 lb. Suppose the road profile is given (in feet) by y(f) = 0.03 sin a)t, where the amplitude of variation of the road surface is 0.03 ft, and the frequency a>depends on the vehicle’s speed and the road profile’s period. Suppose the period of the road surface is 20 ft. Compute the steady-state motion amplitude and the force transmitted to the chassis, if the car is traveling at speeds of 20 and 50 mi/hr.
