So torque equals both Fr and I(rot. accel)?

\[Torque = F(r) = I \alpha\] ?

Can you use them interchangeably in the same equation?

\[\tau = \vec{r}\times\vec{F} = I\alpha\] but torque is not simply a force. It's a force applied at a distance away from a point of rotation. Note that only the NET torque is equal to I alpha, just as only the net force is equal to ma.
