The hood of the automobile is supported by the strut AB, which exerts a force of F = 24 lb on the hood. Determine the moment of this force about the hinged axis y.

If the tension in the cable is F = 140 lb. determine the magnitude of the moment produced by this force with respect to the articulated axis CD of the panel

Determine the Resultant of the forces acting on the T-BAR structure.

The pipe assembly in is secured on the wall by the two brackets. MOA = 60° lb. ft 4 ft 4 ft 3 ft 30⁰ 3 ft Part A If the flowerpot has a weight of 50 lb, determine the magnitude of the moment produced by the weight about the OA axis. Express your answer in pound-feet to three significant figures. ANSWER: B y

The railway crossing gate consists of the 100-kg gate arm having a center of mass at Ga and the 250- kg counterweight having a center of mas at GW. Determine the magnitude and directional sense of the resultant moment produced by the weights about point A. G₁ 2.5 m 0.75 m + Gw 0.5 m 0.25 m 1'm
