Solved: What minimum force F is needed to lift the piano
Chapter 4, Problem 4.76(choose chapter or problem)
(a) What minimum force F is needed to lift the piano (mass M) using the pulley apparatus shown in Fig. 4–66? (b) Determine the tension in each section of rope: \(F_{T1},\ F_{T2},\ F_{T3},\ \text{and}\ F_{T4}\). Assume pulleys are massless and frictionless, and that ropes are massless.
