A wooden door 2.1 m high and 0.90 m wide is hung by two hinges 1.8 m apart. The lower hinge is 15 cm above the bottom of the door. The center of mass of the door is at its geometric center, and the weight of the door is 260 N, which is supported equally by both hinges. Find the horizontal force exerted by each hinge on the door.
One end of a uniform 4.00-m-long rod of weight Fg is supported by a cable at an angle of = 37 with the rod. The other end rests against the wall, where it is held by friction as shown in Figure P12.23. The coefficient of static friction between the wall and the rod is s= 0.500. Determine tile minimum distance x from point A at which an additional object, also with the same weight Fg can be hung without causing the rod to slip at point A.
