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 2.9 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. 2.9 m- 3.23 m E 0.90 m 1.60 m AC 0.6 m Answer: ap = i m/s2
