1. A moving company rigs a pulley system to lift a piano to a fourth floor balcony 44 feet from the ground. The pulley system has 7 ropes with one pulling down and 6 supporting the load and the piano weighs 1200lbs. What is the Ideal MA of this system? Assuming 88% efficiency what is the True MA of this system? Using the True MA, how much force would be required to lift the piano? How much rope would be pulled to lift the plano to the balcony?
