Statics question?

  1. Feb 15, 2009 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations
    F=kx
    and sum of all the vertical and horizontal forces each has to = 0


    3. The attempt at a solution
    Because each end of the spring is like a pin it has an opposing force of 175/2 N on each end to balance out the 175N being pulled in the middle.
    So I took at force and put it in the f=kx equation and solved for x. Which I got to be .175m but i dont see why I did made sense, but i have no idea how to begin this

    Hi kyin01! :smile:

    Begin by calling the distance from the wall x, and taking components. :wink:

    ok i did that, there are no horizontal forces (and by horizontal i mean forces parallel with the wall).

    As for vertical forces I found them to be 87.5 on each side of the pin opposing the direction of the pulling force

    ok … so what's the tension in each spring? :smile:
