Main Question or Discussion Point
I am trying to determine the torque exerted by a motor running a centrifuge at constant speed. How do you determine torque when there is no acceleration? I know it's there somewhere...
I hope you have read what I wrote about the aerodynamic drag before writing this.I understand that a larger torque must be applied to speed up the rotation, but once the system is running at a steady speed (ie no angular acceleration), then the only torque applied is to overcome friction. The two setups should have the same friction because the mass differences are neglible. The force is being applied by a motor via belt to the centrifuge. The application force is not changing between the two.
