Homework Statement


In a hydraulic lever consisting of two ideal fluid lined cylinder/pistons with a fluid filled line coupling the two cylinders, the output force is 100 times the input force. For 1 Joule of work done on the input side, the work done on the output side is (in J):

Homework Equations


AV=AV
Pressure is distributed evenly (Pascal's principle).

The Attempt at a Solution


I have no clue how to proceed.
This is what I had in mind.

You question seems incomplete (and is missing combinations of the letters 'fl' for some reason). What are you trying to find?
 
Oops, good point. I am trying to find the output work - the work done by the output cylinder.
 
Is it true that simple machines do not change the amount of work done but only change the magnitude and/or the direction of the force applied? Because if so that makes this problem extremely easy.
