Therefore, the torque (lbsin or pounds at one inch) requirements will be: torque = (50 (1/10))/2(pi) or 5 / We will leave out the efficiency of the screw/nut combination for simplicity. We get a value of about .7958 lbsin. Now your thinking, that number seems WAY low. That''s because it''s in pound inches and not ounce inches, which is the typical unit in the US for these ratings ...
