Rope BCA passes through a pulley at point C and supports a crate at point A.

Rope BCA passes through a pulley at point C and supports a crate at point A. Rope segment CD supports the pulley and is attached to an eye anchor embedded in a wall. Rope segment BC creates an angle of = 63.0 with the floor and rope segment CD creates an angle with the horizontal. If both ropes BCA and CD can support a maximum tensile force = 700 , what is the maximum weight of the crate that the system can support? What is the angle θ required for equilibrium" see attachment.
