Jamal and Dayo are lifting a large chest, weighing 207 lb, by using the two rope handles attached to either side. As they lift and hold it up so that it is motionless, each handle makes a different angle with respect to the vertical side of the chest (Fig. P5.76). If the angle between Jamals handle and the vertical side is 25.0 and the angle between Dayos handle and the vertical side of the chest is 30.0, what are the tensions in each handle? FIGURE P5.76
The leg and cast in the figure below weigh 250 N, with the center of mass as indicated by the blue arrow in the diagram. The counterbalance wi weighs 110 N. Determine the weight wa and the angle a needed so that no force is exerted on the hip joint by the leg plus cast. 172.4 Your response differs from the correct answer by more than 10%. Double check your calculations. N 62.19 Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. 40
