Homework Statement


http://session.masteringengineering.com/problemAsset/1119613/27/1119613_001.jpg

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 Phi = 55.0 with the floor and rope segment CD creates an angle theta with the horizontal. If both ropes BCA and CD can support a maximum tensile force Tmax = 125 , what is the maximum weight Wmax of the crate that the system can support? What is the angle theta required for equilibrium?


Homework Equations


Not sure

The Attempt at a Solution


I think I need to break it down in the components and go from there, but I am not sure how to factor in the max tensile strength. I would like to use and x-y coordinate system starting at the pulley with positive x going left and positive y going up.

Vector sum of AC and BC equal to CD.
|AC|=|BC|

Sorry, but could you give me a little more direction?
