In the process of changing a flat tire, a motorist uses a hydraulic jack. She begins by applying a force of 45 N to the input piston, which has a radius
r1
As a result , the output plunger , which has a radius
r2
applies a force to the car. The ratio
r2/r1
has a value of 8.3. Ignore the height difference between the input piston and output plunger and determine the force that the output plunger applies to the car.
