Next, determine the threads per inch. Dividing the number of threads by the total length, we get a threads per inch of 2. Finally, calculate the thread pitch. Using the formula P=1/n we find the pitch to be 1/2 = .5 inches.

Webb7 apr. 2016 · $\begingroup$ "In this particular context, where torque is known, the thread pitch doesn't come into it as you are calculating based on the relationship between torque, friction and tension." This statement is incorrect. Screw pitch always comes into it, and it's the quantity that accounts for the mechanical advantage of a screw. $\endgroup$ – http://theoreticalmachinist.com/Threads_UnifiedImperial.aspx scheduled antiepileptic drugs
