(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Please help, anyone. This is not homework as such but rather it is for test preparation.

The biomechanics problem with diagrams is here: http://oregonstate.edu/instruct/exss323/Xtra_Problem4.pdf

As you will note, the answers are already provided. I am only interested in how to come to the answers for parts A and B.

2. Relevant equations

Resultant joint force= The vector sum of all forces acting across a joint.

Resultant joint torque= The sum of the torques

How do we find Fk when angles are involved? Thats throwing me off. Tk also.

3. The attempt at a solution

I already know that the direction of B is clockwise just by looking at the diagram, and that the hamstrings are involved in C.

The Fk and Tk answers are in the above link already but how to get to them is completely uncertain? I am looking for the right process to complete come to the answers provided.

Someone please help :( Thanks
