Solve: (a) and (b) for each object gives and and The top wire has the greatest tension. If then and and 5.3. Set Up: for each object. Apply to each weight and to the pulley. Take upward. The pulley has negligible mass. Let be the tension in the rope and let be the tension in the chain. Solve: (a) The free-body diagram for each weight is the same and is given in Figure 5.3a. gives Figure 5.3 (b) The free-body diagram for the pulley is given in Figure 5.3b. Reflect: The tension is the same at all points along the rope. 5.4. Set Up: For each object use coordinates where is upward. Each object has Call the objects 1 and 2, with and Solve: (a) The free-body diagrams for each object are shown in Figure 5.4. and are replaced by their x and y components. Figure 5.4 (b) For object 2, gives and (c) For object 2,
