The tailgate of a car is supported by the hydraulic lift BC. If the lift exerts a 128-lb force directed along its centerline on the ball and socket at B, determine the moment of the force about A. 15.3 in. 12.0 in. 12.0 in. 2.33 in. The moment of the force about A is 118.93 lb-ft .

Two people exert forces of |F | = 80 lbf and |?| = 50 lbf on the ropes. Determinethe amount of moment of each force about point A. Based on the resultant value, sketch which waythe pole will rotate (i.e., clockwise or counterclockwise) with respect to the point at A.

Determine the sum of the moments of the forces about point O.
