Title: Simple Torque Reduction calculator
Post by: maxhirez on October 18, 2011, 09:36:42 PM
I must not be entering the right search terms in Google.  I'm trying to figure out what the effective lifting capacity of a joint with a servo rated at a given torque will be at various arm lengths.  For simplicity's sake, let's use 350 oz/in.  How would I calculate how many ounces that works out to at various arm lengths between 7-10 in?  Wikipedia and my physics references books have been
USELESS!

Ahemm... I don't think it's the books and Wikipedia that's useless - probably just a 16" error (that's 16" in front of books/screen :D)

350 ozf-in means that it can handle up to 350 oz of force at a distance of 1"
At 5" it's thus 350/5 [oz]
At 8" it's 350/8 [oz]
An so on
