Background -
I am a retired aeronautical and mechanical engineer (70 years old) and closed my consulting/manufacturing firm about 2 years ago. My technical books are still in storage and I can't get to them right now.
A friend has asked me to assist with some machine design calculations and my classes in dynamics were a loooong time ago. While "googling" around I came across this website and hope you can help me.
Problem
I need to calculate the torque required to accelerate and decelerate a 1.5 inch diameter steel shaft through a 540 degree move in 0.35 seconds from start to stop. I am presuming that the calculation would be linear with respect to the length of the shaft. Acceleration may be considered constant for purposes of calculation. Whipping is not considered a problem.
Either the equations or pointing me in the right direction to locate them on the internet would be appreciated. My local library is of very little assistance with this sort of thing and my personal memory bank no longer retains this information in storage.
