An oil pumping rig is shown in the figure. The flexible pump rod D is fastened to the sector at E and is always vertical as it enters the fitting below D. The link AB causes the beam BCE to oscillate as the weighted crank OA revolves. If OA has a constant clockwise speed of 1.0 rev every 3.7 s, determine the acceleration ap (positive if up, negative if down) of the pump rod D when the beam and the crank OA are both in the horizontal position shown.
