Coplanar equilibrium help

    Neglecting friction, determine the tension in cable ABD and the reaction at support C.

    help.. i dont have any idea to solve for the tension so that i could solve for the component force c

    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?
