Find Tension in CD with Input of y

[pHysicsN0OB]

I have to create a formula where one would just need to input y to get the tension from CD.

1. Homework Statement
A worker plans to lift a 60-lb 5 gallon bucket of paint by tying a rope to the scaffold a A and then passing the rope through the bail of the bucket at B and finally over the pulley at C. Please analyze the system assuming that the bucket is held in static equilibrium as it is raised slowly from a height y for 2 ft< y <18 ft.

The Attempt at a Solution

I know on the second picture I'm supposed to put y in the equation but I was just getting an idea how to set up.

Thanks for the post! Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?
