**Physics Classical Mechanics**

remember that the sum of the torques is equal to I*alpha so sigma(t) = r1xF1 + r2xF2 +... +rnxFn = I*alpha where I is the moment of inertia through the axis of rotation. look for I in a table, easily found on google. notice the similarity to the application of Newtons second l...
