A hydraulic lift is used to jack a 970 kg car 12cm off thefloor. The diameter of the output piston is 18com, and the inputforce is 250 N.

a) What is the area of the input piston?

b) What is the work done in lifting the car 12cm?

c) If the input piston moves 13cm in each stroke, how highdoes the car move up for each stroke?

d) How many strokes are required to jack the car up12cm?

e) Show that energy is conserved.
