Problem $05\mathrm{.}070-$ Internal pressure causing a cylindrical tube to yield

An AISI $1030$ cold$-$drawn steel tube has an outside diameter of $50$ mm and an inside diameter of $42$ mm $.$ The tube is $150$

mm long and is capped at both ends.

Problem $05\mathrm{.}070.$a $-$ Use MSS method to calculate the Internal pressure causing a cylindrical tube to

yield

Determine the maximum allowable internal pressure for a static factor of safety of $2$ for the tube walls based on the maximum$-$shear$-$

stress theory.

The maximum allowable internal pressure is

MPa.
