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 ()23817k9.80m/s8.01 10 NBBWmgg===×,the tension force of cable A isTA=×801 103.N.(b) We use the coordinates axes defined in the diagram. Cable A makes an angle of θ2= 66.0º with the negative yaxis, cable B makes an angle of 27.0º with the positive yaxis, and cable C is along the xaxis. The ycomponents of the forces must sum to zero since
