An AISI 1030 cold-drawn steel tube has an OD = 45 mm and wall thickness 5 mm, and the pipe is subjected to internal pressure only. What maximum internal pressure can this tube withstand if the largest principal normal stress is not to exceed 95 percent of the minimum yield strength of the material? Draw a 3D Mohr’s circle for the tube
