1. The problem statement, all variables and given/known data I have an angular acceleration and torque graph. I know it should be a straight line between the points, but my question is, if you extend the line toward the angular acceleration, why it doesn't go to the zero point? It is about 0,6. 2. Relevant equations 3. The attempt at a solution I have thought that there is some other forces that doesn't let the acceleration to be so low. If there is no acceleration, then how there can be any torque? The torque is what's making the accelration as I have learned.
