In theoretical model of ideal XXX. Not when asked to actually calculate something practical unless the ideal model is good enough for constraints.
I am not an engineer. Actually MS in physics however ancient ;)
- jessekv 4y agoIt's an old engineering jibe, of course :) I suspect that the engineer in the GP's story might not remember the equations for angular acceleration, but has an intuitive sense that if a spinning something is in contact with a non-spinning something, you need a good reason for why some of the energy won't get transferred from the former to the latter.
