OK. If then, what is the realistic safety factor I should apply?
The result seems too high.
For 1.500-12UN-2A (and 2B), I get like 2771 ft-lbs of torque.
Yield strength I used is 45,000 psi (Copper alloy)
Sorry for the late response.
Pitch is 0.0833 inch because the threads belong to unified fine thread (1.500-12UN-2A and -2B)
Thread angle is 60 degree (I believe a standard value), so I used alpha value of 30 degree in Motosh equation.
My machinery handbook tells me to calculate the yield...
Hello all
I'm trying to calculate a torque needed to tighten a threaded terminal. (Both male and female parts are copper alloy)
I'm using Motosh's equation which requires me to use the coefficient of friction.
Web sources tells me that the copper-copper coefficient of friction is 1.0.
The...
