Repeat Prob. 3100 with an OD of 2 in and wall thickness of 0.25 in. Repeat Prob.

Question:

Repeat Prob. 3–100 with an OD of 2 in and wall thickness of 0.25 in.
Repeat Prob. 3–100, An AISI 1040 cold-drawn steel tube has an OD = 50 mm and wall thickness 6 mm. What maximum external pressure can this tube withstand if the largest principal normal stress is not to exceed 80 percent of the minimum yield strength of the material?
