Fluid Mechanics: Hydraulic Lift

  1. Jan 24, 2006 #1
    Hi,
    I have here a problem that I've been working on, and am not sure if I've gone about it correctly. The method I chose seems too simple, and I was wondering if someone could go over the answer that I've found, and let me know if I'm doing this right.


    The problem:
    The piston of a hydraulic automobile lift is 0.30m in diameter. What guage pressure, in pascals, is required to lift a car with a mass of 1200kg?

    First off, I just calculated it in Pascales, and haven't done the guage pressure thing yet, but this is the answer that I have come accross (Attached)

    Again, this seems too simple... If I'm going about this the wrong way, I think I'm just having difficulty organizing the problem. Am I going in the right direction?


    Thanks,
    HM
