The allowable tensile force on drill pipe is often adjusted to account for the make-up torque that is applied while screwing neighboring segments together. Consider a drill pipe with a 5 in. outer diameter and 4.408 in. inner diameter.

(a) If the yield stress of the pipe in tension is 100000 psi, what is the allowable tensile force on the pipe disregarding the make-up torque?

(b) Say the make-up torque is 26000 lb-ft. What is the allowable tensile force when the make-up torque is accounted for?
