A hydraulic lift is used to jack a 1120kg car 10 cm off the floor. The diameterof the output piston is 18 cm, and the input force is 250 N.
(a) What is the area of the input piston?
m2
(b) What is the work done in lifting the car 10 cm?
J
(c) If the input piston moves 13 cm in each stroke, how high doesthe car move up for each stroke?
m
(d) How many strokes are required to jack the car up 10 cm?
(e) Calculate the combined work input of all of the strokes.
