Thee foot segment is subjected to the pull of the two plantarflexor muscles. Determine the moment of each force about the point of contact A on the ground.
I've used others to help determine certain angles, but I'm not sure if it was even necessary.
The Attempt at a Solution
I have been able to calculate most of the angles, but I'm not exactly sure where to go from there. Which force do I use when?
Is it something like (20cos(60))(30cos(70))-(20sin(60))(30sin(70))? No idea if I'm on the right track or anything.
I need help! My professor is almost as bad as the book he had us buy..
