All students Torque Center of Mass Lab

Most of you missed the point about how do the meter stick and weights satisfy the condition for sum of the Fs to equal zero. Many of you cite the fact that a = 0. This is claer evidence that the sum of the forces does equal zero, but it does not explain why this so.

The fact that the net torque is zero does not mean the sum of the forces is zero.
