# In desperate need of help with this statically indeterminable problem

## Homework Statement

http://img855.imageshack.us/img855/5648/fbds.png [Broken]

Basically I am analysing the human leg in the given position. I need to find the force (F) which is exerted at point C, when the person is in such a position. Point B represents a "pin connection" at the ankle, body AB is the shin, BC - the thigh. All masses and distances are known.

## Homework Equations

These are the main equations of static equilibrium for the two bodies.

Unknowns: Bx,By,N,Ax,Mb,Mc,F.

## The Attempt at a Solution

That was my attempt, I am not looking for a numerical solution, just some help with how should I continue... If this truly is a statically indeterminable problem, I don't think that the method of superposition or other deviation related methods could help... Any input would be greatly appreciated. Even if it includes pointing out a stupid mistake of mine.. :D Thanks, guys!
