5.5.Set Up:Take upward. Apply to the person. Solve: (a)The free-body diagram for the person is given in Figure 5.5. The two sides of the rope each exert a forcewith vertical component gives Figure 5.5(b)Set and solve for and Reflect:Only the vertical components of the tension on each side of the person act to hold him up. The tension inthe rope is much greater than his weight.5.6.Set Up:Use the coordinates shown in Figure 5.6. The wall exerts a force Ton each end of the chain, where Tis the tension in the chain at each end. is tangent to the chain at each end.Figure 5.6Solve: (a)The free-body diagram for the chain is shown in Figure 5.6. The force at each end is resolved into its xand ycomponents.(b)gives
