55. (a) The forces acting on bucket are the force of gravity, down, and the tension force of cable A, up. Since the bucket is in equilibrium and its weight is () 23 817k 9.80m/s 8.01 10 N BB Wm g g == = × , the tension force of cable A is T A 801 10 3 .N . (b) We use the coordinates axes defined in the diagram. Cable A makes an angle of θ 2 = 66.0º with the negative y axis, cable B makes an angle of 27.0º with the positive y axis, and cable C is along the x axis. The y components of the forces must sum to zero since
