[I've searched the site and did google. I couldn't find a satisfactory answer]
I have the motor characteristics and the moment of inertia of the object I'm supposed to spin with it. I have to design the shaft considering the torsional failure.
Now, if I consider the inertia of the body, there is a small difference in rotational displacements, for example, consider starting the motor. The motor is at spin but the body isn't spinning yet. This yields a torsion to the shaft. What is the maximum value of the "difference" that can be allowed? How do I state these mathematically and find the diameter of the shaft? What are the parameters?
