Physics help problem-component force and finding X distance?

  1. May 7, 2013 #1
    1. The problem statement, all variables and given/known data
    have set up my diagram but I am unsure how to approach each problem.

    For this first picture http://tinypic.com/r/25i9gkh/5

    I just need to find By and Bx

    for the second picture http://tinypic.com/r/25i9gkh/5

    I need to find the distance of x.

    Thanks to anyone who is willing to help.


    2. Relevant equations

    Not sure...

    3. The attempt at a solution

    Ax = Bx

    By + Ay = 850N + 882.63N

    B y (20m) = 850N(5m) + 882.63N(10m)

    Here is my diagram of the first question http://tinypic.com/r/25i9gkh/5
    ----------------------------------------------------------------------------------------------
    For the second question I know: 2B = 420 + 640 + 180

    Here is the picture, I have to find X

    All of your pictures are the same. (And they have the same URL) It is not clear what distance 'x' you are trying to find.

    If you are trying to put this system into static equilibrium, then write an equation for the sum of the forces and an equation for the moments about a convenient point. For this case, I would suggest you use the right end where B is located.
