Problem 5.33 (Multistep) In the dark in outer space, you observe a glowing ball of known mass 4.6 kg moving in the plane at constant speed in a circle of radius 7.5 m, with the center of the circle at the origin (<0, 0, 0> m). You can't see what's making it move in a circle. At time 0 the ball is at location <7.5, 0, 0> m and has velocity <0, -80, 0> m/s.

The car hoist allows the car to be driven onto the platform, after which the rear wheels are raised. if the loading from both rear wheels is 1380 lb, determine the force in the hydraulic cylinder ab. neglect the weight of the platform itself. member bcd is a right-angle bell crank pinned to the ramp at c. the force is positive if in tension, negative if in compression.
