Medical Physics: Calculating Traction, Tension and Reaction Force

[tamimi23]

Q: how can i determine the Traction Force, (Tension) in the rope and the Reaction Force of the leg muscles to the reaction. Neglecting all friction of the pulleys so that they do not affect the tensions in the ropes??

I need a formula for: Traction force, Tension, and Reaction Force.

Given: 60 degrees, and a load of 4kg.

Pulleys? Tension? Leg muscles? I hope you're not up to anything too evil!

Seriously though, can you give us the full question? Include any diagrams; they're crucial to understanding the problem.
