Well the entire system is in equilibrium since there is no movement. Therefore the sum of all the Torques = 0 and the sum of all the Forces =0. The forces are 1) the force of gravity going down point A (the center of gravity) 2)the Force exerted by the should on the humerus and 3) the force of...
I'm having a hard time with this rotational equilibrium problem: There is an attached image that shows the free-body diagram.
The arm in the figure weighs 36.0 N. The force of gravity acting on the arm acts through point A. Determine the magnitudes of the tension force Ft in the deltoid...
