Answer to Question #18432 in Mechanics | Relativity for Janice
A lever is used to lift a heavy load. When a 52 N force pushes the left end of the lever down 1.28 m, the load rises 0.23m.
1) What is the ideal mechanical advantage of this lever?
2) What is the work input?
3) Calculate the weight of the load if the lever is 100% efficient
