How Does Non-Linear Friction Affect Torque in Drilling?
Hi nvn, thanks that helps a lot. I see "frictional torque" doesn't appear to be a very well covered topic. I was surprised to see that it is a function of the dimensions of the contacting area. Could you please guide me to a derivation of frictional torque ? I would like to find an expression...- Sumtwit

How Does Non-Linear Friction Affect Torque in Drilling?
Hi everyone. This is not a homework problem. I am very familiar with the case of linear(direction) friction. F_{friction}=\mu F_{normal} ...(1) However my question is closer to something like this: \tau_{friction}=\beta F_{normal} ...(2) Where \tau_{friction} is a torque Imagine if a...- Sumtwit
