Homework Help: Springs - simple harmonic motion

  1. Jul 12, 2008 #1
    my question is: is there a way to find the work done to a spring when the only variable given is the distance (x)??

    1. The problem statement, all variables and given/known data
    For the pressure gauge, what work is done by the air on the spring?

    2. Relevant equations
    W = 1/2kx2
    Fx = kx

    3. The attempt at a solution
    I cant really attempt anything because i dont have k, its not given and im not sure how to find it??

    If it is a pressure gauge what is it you would expect such a device to do? Will it measure say something like the pressure of the air? When it does that will it give a reading? What work will the air have done to affect that reading from the normal state?

    Is there a diagram and more to the problem or just a general question about what work air pressure does inside a gauge?

    The question doesnt give any other information so i think your right, they just want a general answer. thanks i was freaking out cuz they didnt give enough info!!
