Physics: Torque and static equilibrium

    I don't like writing formulas on the computer, so i just scanned my attempt.

    In my working out, i incorrectly use the mass of 21kg for the light, it's actually 21.5kg....but either way my working out is still incorrect.

    Thanks in advance, Frantelle.

    Look closely at the diagram, does the tension in the cable actually have a component in the y-direction?
