A dentist’s chair with a patient in it weighs 1820 N. The output plunger of a hydraulic system begins to lift the chair when the dentist’s foot applies a force of 63 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?
