Determine the velocity and acceleration of point C located on the double collar when at the position shown. The collar consists of two pin-connected slider blocks which are constrained to move along the circular path and the rod AB . Given: 3 rad s = θ 45 deg = r 0.4 m = Solution: Guesses v rel 1 m s = v C 1 m s = a rel 1 m s 2 = a Ct 1 m s 2 = Given v C sin 2 () cos 2 0 v rel cos sin 0
