Homework Help: Physics

Hi,

I try to solve this problem with this formula and I can not get the right answer !

F2 = F1 ( R2/R1)

A dentist's chair with a patient in it weighs 1790 N. The output plunger of a hydraulic system begins to lift the chair, when the dentist's foot applies a force of 51.5 N to the input piston. Neglect any height difference between the plunger and the piston. What is the ratio of the radius of the plunger to the radius of the piston?

I got it !

Thanks
