Homework Help: Static Equilbrium

  1. Apr 29, 2008 #1
    1. The problem statement, all variables and given/known data
    The system at the right is in static equilbrium, and the string in the middle is exactly horizontal. Find a) tension T(1) b) tension T(2) c) tension T(3) d) angle thetas

    **I don't know if anyone can help me with this because I cannot upload the picture. Any help is appreciated.

    2. Relevant equations
    T(ax)=-T(a) cos 60
    T(ay)=T(a) sin 60
    Sun(Ty)=T(a)sin60-(3 kg)(9.8)=0
    =(3kg)(9.8)/(sin60)
    =33.95 N

    Sum(tx)=T(b)-T(a)cos60=0
    T(b)=(3.4kg)(g)(.5)
    =16.66 N

    Now, I am unsure how to find T(3) and theta.'

    Thanks.

    3. The attempt at a solution
