The pin A in the bell crank AOD is guided by the flanges of the collar B, which slides with a constant velocity v_B of 3 ft/sec along the fixed shaft for an interval of motion. For the position θ = 30° determine the acceleration of the plunger CE, whose upper end is positioned by the radial slot in the bell crank.
