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 3500kg, plus the 550kg platform on which they are parked. To avoid injury to your workers, the maximum amount of force a worker should need to exert is 100NA) what should be teh diameter of the pipe under the platform. B)if the worker pushes down with a stroke of 50.0 cm long, by how much will he raise the car at the other end?
