29. (III) A door 2.30 m high and 1.30 m wide has a mass of 13.0 kg. A hinge 0.40 m from the top and another hinge 0.40 m from the bottom each support half the door's weight (Fig.9-69). Assume that the center of gravity is at the geometrical center of the door, and determine 2.30 m the horizontal and vertical force components exerted by each hinge on the door. 40 cm 1.30 m T40 cm FIGURE 9-69 Problem 29.
