The elements of a switching device are shown. If the vertical control rod has a downward velocity v = 3.6 ft/sec and an upward acceleration a = 2.4 ft/sec when the device is in the position shown, determine the magnitude of the acceleration of point A. Roller C is in continuous contact with the inclined surface. 7" a 30 B 7" 15 X Part 2 Find the magnitude of the acceleration of point C and the magnitude of the angular acceleration of the rod. Answers: ac= ft/sec = rad/sec Attempts: 0 of 3 used
