The pumping unit is used to recover oil. When the walking beam ABCABC is horizontal, the force acting in the wireline at the well head is FCFC = 250 lb. lb. Determine the torque MM which must be exerted by the motor in order to overcome this load. The horse-head CC weighs 61 lblb and has a center of gravity at GCGC. The walking beam ABCABC has a weight of 130 lblb and a center of gravity at GBGB, and the counterweight has a weight of 225 lblb and a center of gravity at GWGW. The pitman, ADAD, is pin connected at its ends and has negligible weight.
