5. Two identical, uniform beams of length 3 m and weighing 260 N each are
connected at one end by a frictionless hinge. A light horizontal crossbar, attached at the
midpoints of the beams maintains an angle 50° between the beams. The beams are
suspended from the ceiling by vertical wires so they form a V. See figure. (a) What force
does the crossbar exert on each beam? (b) Is the crossbar under compression or tension,
i.e. are the ends of the crossbar being pushed together or stretched farther apart? (c) What
force (magnitude and direction) does the hinge exert on each beam?

One end of a uniform - 3.60-m-long rod of weight w is supported by a cable at an angle of 6-37° with the rod. The other end rests against a wall, where it is held by friction (see figure). The coefficient of static friction between the wall and the rod is,-0.460. Determine the minimum distance x from point A at which an additional weight w (the same as the weight of the rod) can be
hung without causing the rod to slip at point A
