Problem 4.3 The uniform, horizontal beam shown in Figure 4.51is hinged to the wall at A and supported by a cable attached to the beam at C. C also represents

the center of gravity of the beam.At the other end, the cable is attached to the wall so that it makes an angle = 68° with the horizontal. If the length of the beam is l = 4 m and the weight of the beam is W: 400 N, calculate the tension T in the cable and components of the reaction force on the beam at A.=
