1. The problem statement, all variables and given/known data 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. 2. Relevant equations M=Fd I've used others to help determine certain angles, but i'm not sure if it was even necessary. 3. 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..
