Try forgetting that there's a string and a pulley; think instead of a force T acting upward at the LHS of the horizontal part of the frame and a force T acting leftward at the top of the vertical part of the frame.

[Forget also that the leftward force would make the frame slide on the fulcrum! Think of it as a hinge instead]

Can you write the sum of moments?
