6-57 Pulleys A and B of the chain hoist shown in Fig. P6-57 are connected and rotate as a unit. The chain is con- tinuous, and each of the pulleys contains slots that prevent the chain from slipping. Determine the force F required to hold a 1000-lb block W in equilibrium if the radii of pul- leys A and B are 3.5 and 4.0 in., respectively. B W
