a) The location of pitch and bounce oscillation centers.
b) The natural frequencies of the pitch and bounce motion of the vehicle body.
c) If the above vehicle travels over a concrete highway with the expansion joints 65 ft apart, calculate the speeds at which the bounce motion and the pitch motion of the vehicle body are most likely to rise.

Problem 2 NAME For the vehicle with the following information calculate: a) The location of pitch and bounce oscillation centers. b) The natural frequencies of the pitch and bounce motion of the vehicle body. c) If the above vehicle travels over a concrete highway with the expansion joints 65 ft apart, calculate the speeds at which the bounce motion and the pitch motion of the vehicle body are most likely to rise. Combined front suspension springs stiffness = 254 lb/in Combined rear suspension springs stiffness = 184 lb/in Front axle load = 1914 lb, Rear axle load = 1650 lb Wheelbase = 112 in, Distance from front axle to the center of gravity (h) = 49.68 in Radius of gyration about a horizontal transverse axis at the center of gravity = 57 in.
