Hello all, I am brand new to this forum and I am here for one topic that I need some explanation on. I am an AH-64D Attack Helicopter Technical Inspector and I have been in an on-going discussion/argument over the subject of run-on torque addition to required torque for self locking nuts. Short explanation follows:
Maintenance manual calls for Nut (A) to be installed on Bolt (B) with a required torque of 1000 inlbs.
Nut (A) is a self locking nut with a run-on torque of 75 inlbs.
Run-on torque has been established using a dial indicating torque wrench with bolt (B) fully extended through Nut(A).
Question 1: Will the 75 inlbs of run-on torque be added to the required torque of 1000 inlbs for a total applied torque of 1075 inlbs?
Question 2: What is the Physics explanation behind this answer.
Thanks for any assistance
