You are a dentist who is about to do a procedure on a patient. The dentists’ chair which is an example of a hydraulic-lift system and is 230.0 kg rests on a piston with a cross-sectional area of 1 530 cm^2. If the cross-sectional of the input piston you are stepping is 81 cm^2, what force must you apply to the input piston to lift the chair?
