Equilibrium normal reaction force problem

  1. Oct 8, 2007 #1
    1. The problem statement, all variables and given/known data

    3. The attempt at a solution
    This should be easy, but I'm tired and just can't do it. If anyone can point me in the right direction that'd be great. I tried making a FBD, and had the equations:
    [tex]Tsin30^{\circ} - 752N = 0[/tex]
    [tex]344N - Tcos30^{\circ} = 0[/tex]

    But, that then gives me two different answers for T. So I'm lost.

    note: the question asks you about the normal reaction force, doesn't that give u a hint?

    Is the answer 752N?

    first identify all forces acting on the ball, draw a force diagram and then balance them.
    there should be 4 different forces acting on the ball

    Haha, well that means I got the question wrong. Damn.

    [tex]Tsin30^{\circ} - 752N = 0[/tex]
    [tex]344N - Tcos30^{\circ} = 0[/tex]

    ?
