A hydrolic lift (starting with both pistons at the same height) isused to jack a 970kg car 12cm off the floor in steps. The diameterof the output (lift) piston is 18cm and the input force is250N.
a) What is the area of the input (compression)piston?
b) What is the total work necessary to lift thecar 12cm? Recall that W=Fd.
c) If the input piston moves down 13cm in eachstroke, how high up does the car move with each stroke of the inputpiston? Use the fact that the same amount of work is done by theinput and output pistons in each stroke.
d) How many strokes of the input piston does ittake to jack the car up the full 12 cm?
e) What is the total amount of work done by theinput piston? Base your answer on the number of strokes, thedistance of each stroke, and the input force.
