Physics
A dentist's chair with a patient in it weighs 2260 N. The output plunger of a hydraulic system begins to lift the chair when the dentist's foot applies a force of 61 N to the input piston. Neglect any height difference between the plunger and the piston. What is the ratio of ...

a hydraulic jack is used to move an 8896 newton car. if the area of the output piston is 8 times that of the input piston, how much input force is required to lift the car. i did Pi * 8 them multiplied that answer * 8896 then divided that answer times 8896. i dont think that ...
