Hello guys, i need some enlightenment (help) to solve this problem
, maybe someone here have mastered physics or engineering can help me to break this problem !
I already tried to seek the answer, but i face dead end and really frustating because of it
.
So the problem is "how to get calculation / equation for calculate torque (delta torque) on "Multi Lobe Torque Ring (MLT Ring)" as picture above.
Name of thing above is MLT Ring "blue coloured", it is installed inside Casing/Tubing threaded for oil well, and the main function of this ring is to boost value of torque on Casing/Tubing, so it can endure more torque with it.
From that explanation we know that there two kind of torque on it, torque of the casing/tubing threaded and torque of ring.
The reference/book that designed/made/fabricated this "MLT Ring" is just explaining how they get number of ring torque in very common,
Different with torque of Casing/Tubing, it has reference equation to get exact number of it torque,
Above is equation to get torque of casing/tubing, initially i think this equation will be the same equation to calculating how much torque on ring because as you see, between ring and casing/tubing they are connected in one line, but i tried and it is not same as the table.
In this book also has already table of both torque, for casing/tubing and ring but what i need is the exact explanation or philosophy why they get that number, from where ?
Material of ring : L-80 (yield strength 80.000 psi)
OD : 2-3/8"
ID: in the table
Maybe someone here want to help me to solve it![Angel :angel: :angel:](https://www.physicsforums.com/styles/physicsforums/xenforo/smilies/oldschool/angel.gif)
