Question: A farmer has to lift up a 2000lb boulder 12 inches in the air in order to put it in his wagon. he has a fixed and movable pulley with a rope, an 8 foot long, 12in high incline plane and a 10 foot long lever with a maximum push or pull force of 100lbf. I need a system that can lift the boulder on the wagon with an ima for each machine, a compound one and an ideal effort force for the compound machine. What are some ideas that would work?   Edit
