Calculating Torque to Turn a Rod    1. I am working on a senior
design project, and we need to calculae the torque needed by a
DC motor to turn a threader rod. Any ideas as to how to
calculate the torque needed to turn a rod? .75" Diam., 1ft
length, will be lifted/lowered up and down at 90° to level
ground. I know I'm new, but any help is appreciated!   2. jcsd
3. Any torque will turn a rod overcoming friction, how much is
the question?  Have something to add?
