Engineering Mechanics - Dynamics Chapter 20 v B 12 ft s = a B 96.5 ft s 2 = Problem 20-22 Rod AB is attached to a disk and a collar by ball-and-socket joints. If the disk is rotating at a constant angular velocity ω , determine the velocity and acceleration of the collar at A at the instant shown. Assume the angular velocity is directed perpendicular to the rod. Given: 2 rad s = r 1f t = b 3f t = Solution: Guesses α x 1 rad s = ω x 1 rad = ω y 1 rad = α y 1 rad s = ω z 1 rad = α z 1 rad s 2 = v A 1 ft s = a A 1 ft s 2 = 0 ω r 0
