Re: Torque?

What causes some confusion it in SI units, torque is expressed as Newton meters, which is the same unit as a Joule (work). But torque is not the same as work although they have the same unit. Until you multiple torque by radians traveled. Through the magic of unitless numbers, you get work.

As for what units to use... If you live in the states, get used to working in both because it is going to be a missmash for the foreseeable future.

Thinking about Lb mass verses lb force gives me a head ache so I never use lb mass. I have not used a slug since school. I do have mechanics use a slugging wrench to tighten bolts. Does that count?
