The arm in the figure below weighs 37.6 N. The force of gravity acting on the arm acts through point A. Determine the magnitudes of the tension force F, in the deltoid muscle and the force i, exerted by the shoulder on the humerus (upper-arm bone) to hold the arm in the position shown. (Enter your answers to at least the nearest newton.) N %3D 0.080 m 0.290 m-

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-

The system in the Figure is in equilibrium. A mass M1 = 246.0 kg hangs from the end of a uniform strut which is held at an angle theta = 40.0o with respect to the horizontal. The cable supporting the strut is at angle alpha = 24.4o with respect to the horizontal. The strut has a mass of 58.2 kg. Find the magnitude of the tension T in the cable. Find the magnitude of the horizontal component of the force exerted on the strut by the hinge? Find the magnitude of the vertical component of the force exerted on the strut by the hinge?
