A fixed crane has a mass of 80 kg and is used to lift a 200 kg crate. It is held in place by a pin at A and a rocker at B. The center of gravity of the crane is located at G. Determine the reaction forces at A and B. (g = 9.81 m/s2) (Rigid Body Equilibrium) 1 2 m B 3 m 200 kg/ 5 m

Determine the force in each member of the truss and indicate if the member is in tension or compression. 700 lb 2 ft B 700 lb 2 ft D

A basketball player weighing 200 lb hangs on the rim of the basketball hoop shown below. The vertical post ABCD is fixed at support D and weighs 100 lb with its center of gravity at point C. The backboard hoop assembly weighs 60 lb with its and its center of gravity is located at point G. Determine the support reactions at D and forces acting at pins E and F. Neglect the weights of members AE, IF, and IJ.

A force of 1000 lb is applied to the 600-lb horizontal beam supported by a hinge at A and a roller at B on a smooth surface. If the pin support at A suddenly fails, calculate the magnitude of the force of the roller at B acting on the beam at that instant, by modelling the beam as a uniform slender bar. Present your answer in lb using 3 significant figures. 4 13 1000 lb -8 ft- B -2 ft-
