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 problem is that coefficient of friction value of 1.0 gives me a torque value that seems to be too high. Can anyone advise me on this issue? Thanks.
