Suppose you use an ideal pulley of the type shown in Figure 5.18(a) to support a car engine of mass 120 kg. MA = 2 MA = 3 MA = 4 W W TTTT W (a) Figure 5.18 (a) What would the tension in the rope be? 294 X N (b) (c) (b) What force must the ceiling supply, assuming you pull straight down on the rope? Neglect the pulley system's mass. 935.9 XN (upward)
