Just watching a bearing hub replacement which required a 46 pound-feet of torque with an additional 120 degrees to get it done proper.
Why did they add the angle torque addition instead of just giving the adjusted foot pound of torque? For example, perhaps 46 pound-feet + 120 degrees would finally end up becoming 80 pount-feet of torque. So why not just give us a spec which says 80 ft-lb ( + 0 degrees ) ?
I guess in essence the question is: is there 1:1 relationship between torque+roation with a specific torque value?
