An 80 kg person stands on a cylindrical piston of diameter 0.50 m. This piston is part of a hydraulic lift which has a lift piston 1.0 m x 2.5 m in size. A) What pressure does the person standing on the piston apply to the uid in the lift? B) What force will the lift apply to the lift piston? C) If the person's weight were doubled and the output piston area were tripled, by what factor would the output force change
