Homework Help: physics

Posted by kate on Monday, February 23, 2009 at 1:59am.

You are designing a hydraulic lift for an automobile garage. It will consist of two oil-filled cylindrical pipes of different diameters. A worker pushes down on a piston at one end, raising the car on a platform at the other end. To handle a full range of jobs, you must be able to lift cars up to 4000kg, plus the 600 kg platform on which they are parked. To avoid injury to your workers, the maximum amount of force a worker should need to exert is 100N.What should be the diameter of the pipe under the platform?

Can someone please explain how i should do this problem I have no idea
