The piston 1 in the figure at right has a radius of r1 and is located a distance x from a pivot.

Piston 2 has a radius of r2. (a) draw a free body diagram of the forces acting on the lever.

(b) What force F must be applied at distance L to lift the mass M located above piston 2?

Assume the two pistons are at the same level.
