30 A 50 kg truck engine is lifted using the setup shown. Assuming that the pulleys are frictionless, What force P must be applied to the cable to hold the engine in the position shown with d= 1m? (Hint: because the frictionless pulleys, the tension in the cable will be uniform through out the whole length of the cable.) 2.
