Homework Help: Rigid Body questions

  1. Nov 18, 2007 #1
    1. The problem statement, all variables and given/known data

    thin uniform metal rod is bent into three perpendicular segments, two of which have length L . You want to determine what the length of the third segment should be so that the unit will hang with two segments horizontal when it is supported by a hook

    u <--hook
    L
    ---------
    | L
    |
    ----------------
    x
    2. Relevant equations

    Torque = 0

    3. The attempt at a solution

    I tried to do three seperate torques, T1 = L T2= L2 and T3 = X but i don't know how to solve

    its a backward C

    the top and perpendicular part is length L and the bottom length X which is what we are looking for in terms of L

    It looks like ______ <--- L
    ..........................|
    ..........................| <--- L
    ..........................|
