Adentist's chair with a patient in it weighs 1580 N. The output plunger of a hydraulic system begins to lift the chair, when the dentist's foot applies a force of 51.0 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? Output plunger In the process of changing a at tire, a motorist uses a hydraulicjaolc She begins by applying a force of 54 N to the input piston, which has a radius r1. A5 a result, the output plunger. which has a radius r2, applies a force to the car. The ratio rgirI has a value of 9.1. Ignore the height difference between the input piston and output plungerand determine the force that the output plunger applies to the car
