Question in probably the wrong forum, but...

which equals 40 ft lbs like I said.    in lbs * .0833 = ft lbs

No thats the equation to convert foot pounds to inch pounds...

Try again...

No,  I suggest you do because you still have it backwards. Try a real source of info like a physics manual like I did instead of google.    But if you must use the internet as a source try this one as it's at least accurate. The question stated the arms were 1 foot long.    40 ft lb = 480 in lbs  same thing!

http://en.wikipedia.org/wiki/Foot-pound_force   1 ft. lb = 12 in. lbs

DOH! I was thinking if the motor is reciving a total of 480 pounds @ one inch from the axle, then you would take your one inch of force and times it by 12 to get your foot pounds of force, but I guess I did have it totally backwards! Kinda counter intuitive.
