150 sounds like a guess? Got the formula?

 

I obviously did'nt do any calculation, it is just because 150 ft.lb is roughly the maximum capacity of my dynanometric key.

When I was a student in the early 70's, our teachers told us that about 80% of the parts were not calculated but estimated empirically! Among the 20% calculated, many were by hand because personal computers did not exist, there were only large computers which were expensive,  relatively slow and were used only for the calculations of the main and complicated parts.
