Here is the problem which I am struggling on, please help me!
Problem: Dave's foot (mass = 1.019 kg) is in contact with the ground and at static equilibrium. The ground reaction force in the x direction is 143 N and in the y direction is 791 N. The coordinates of the ankle joint are -0.045, 0.053 m and the coordinates of the center of pressure of the ground reaction force are 0.05, -0.046 m with the origin of our reference frame at the center of mass of the foot.
1- What is the torque (Nm) produced by the muscles that span the ankle?
I need expert help to solve the above question and thanks in advance.
