Answer(s):
As the hydraulic cylinder rotates around O, the exposed length l of the piston rod is controlledby the action of the oil pressure in the cylinder. If the cylinder rotates at the constant rate ofdθ/dt = 55 deg/s and l is decreasing at the constant rate of 155 mm/s, calculate the magnitudesof the velocity v and acceleration a of end B when l = 125 mm.
As the hydraulic cylinder rotates around O, the ex-
posed length l of the piston rod P is controlled by
