Follow-up Question
This is a follow up to my question and the answer you submitted.
The equation you used for J is wrong, not sure how you got J=π32×Do4-Di4,
the equation should be J=π/2×ro4-ri4 which is J=pi/2(50^4-40^4) = 5.8e+6 mm^4
Solution
Follow-up Question
The problem I am solving shows a point B on the OD of the pipe that lies on the z-axis. When using the equation tau =(Mr)/J, I get 15.5 MPa, not 124 MPa
