How do you calculate the resistance, friction and torque required to rotate a steel tube which is 50% concrete in contact with
the weight of the tube is the only charge. The water used to cool the heat of friction. It's a little sampler for concrete. I know that the torque needed to reduce friction, but is beginning to be aware that you go deeper.
I think * this is very simple, because the weight of the tube is made of drilling / cutting bit. The only things you should consider are: the coefficient of friction of steel concrete and pipe area involved, and the tangential force in the pipeline. This this depth will affect the strength and endurance, such as heat. In addition, other factors such as the drill "tilt" that probably will make this kind of dating useless.
