Problem Statement Based on Problem 4-59 from the textbook. The board is used to hold the end of the cross lug wrench in the position shown. If a torque of 30 N*m about x axis is required to tighten the nut, determine the required magnitude of the force F needed to turn the wrench. Force F lies in a verticla plane. = 280 mm b=235 mm -Fach Student: b Z 60° a - y

The pumping unit is used to recover oil. When the walking beam ABC is horizontal, the forceacting in the wireline at the well head is 250 lb. Determine the torque M which must beexerted by the motor in order to overcome this load. The horse-head C weighs 60 lb andhas a center of gravity at Gc. The walking beam ABC has a weight of 130 lb and a centerof gravity at GB, and the counterweight has a weight of 200 lb and a center of gravity atGW. The pitman, AD, is pin connected at its ends and has negligible weight.
