Homework Statement
A man of Mass M stands on a railroad car that is rounding an unbanked turn of radius R at speed v. His center of mass is height L above the car, and his feet are distance d apart. The man is facing the direction of motion. How much weight is on each of his feet.
Homework Equations
I have solved the problem too ensure that the torque about the center of mass is zero. What I don't understand is why the torque about the center of mass being zero ensures that the torque about any point is zero. I know that this is the case if there are no net forces acting, but that isn't the case here.
