3. 5. 13. A boom AB is supported in a horizontal position by a hinge A and a cable which runs from C over a small pulley at D as shown in Figure
P3.5.13. Compute the tension T in the cable and the horizontal and vertical components of the reaction at A. Neglect the weight of the boom
and the size of the pulley at D.
3-5.14. Repeat Prob. 3-5.13 if the cable pulls the boom AB into a
position at which it is inclined upward at a slope of 4 vertical to 3 horizon-
tal. The loads remain vertical.
