Write up an explanation on how to do an 'equilibrium' problem going through each of the steps and different situations. Then apply this knowledge to complete the following problem. Problem: Jim Bob is showing off his awesome biceps in the gym by doing curls. Assume that his elbow acts as a pin and that his arm has a mass of 2 kg and is uniform, so the force of gravity acts its center of its 13 inch (.33 m) length. Treat the muscle as a tension force acting straight up connected 1.5 in (0.037 m) from the elbow. Finally, he is lifting a 50 lb (22.7 kg) mass in his hand. Calculate all forces acting on the arm.

A bridge, constructed of 11 beams of equal length LLL and negligible mass, supports an object of mass MMM as shown. (Figure 1)Real bridges of this sort have steel rockers at the ends (check one out sometime), these assure that the support forces on the bridge are vertical even when it expands or contracts thermally. Throughout this problem, use g for the magnitude of the acceleration due to gravity. A. Assuming that the bridge segments are free to pivot at each intersection point, what is the tension T in the horizontal segment directly above the point where the object is attached? (Figure 2)If you find that the horizontal segment directly above the point where the object is attached is being stretched, indicate this with a positive value for T. If the segment is being compressed, indicate this with a negative value for T.
