1. The problem statement, all variables and given/known data

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):

2. Relevant equations

AV=AV

Pressure is distributed evenly (Pascal's principle).

3. 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.
