Gymnast equilibrium

    [SOLVED] Gymnast equilibrium

    1. The problem statement, all variables and given/known data
    A gymnast of mass 65.0kg hangs from two fixed rings as shown in the diagram.
    The gymnast is stationary and the support ropes make an angle of 5.0degrees to the vertical.

    Calculate the tension in each of the support ropes.

    2. Relevant equations
    \sum {F_{up} } = \sum {F_{down} }

    3. The attempt at a solution
    Well I have drawn a free body diagram.
    Is this attempt correct?

    \sum {F_{up} } = \sum {F_{down} } \\
    2\left[ {T\cos 5} \right] = 65 \times 9.8 \\
    \Rightarrow T = 3.20 \times 10^2 N{\rm} \\
    in each rope

    Thanks in advance
