I was wondering if you could help me out. I need help on how to calculate joint reaction forces, ground reaction force and torques.
Basically I'm doing a mini project on runners with a forefoot strike vs. heel strike for my biomechanics class. I have two pictures of the same runner one doing a heel strike, and one doing a foot strike. I've made free body diagrams of them, (two link models, separating the foot and the lower leg).
And I have an anthropometric table, so that I can measure the segments and use the table to figure out the Center of Mass for the segment.
I guess I'm just not getting where the angles come into play . And I have to put in my own numbers/data cause there is none available. So I am gonna go by the assumption that this runner is 150 lbs.
Here are the pictures:
