I’ll try for the gold ring first and then come back to earth. Trying to find out the max forces to snap a pipe in-half (torsion problem) I have a 3”OD mechanical round tube with 1/4” wall its (ASTM-A 519) grade and 20ft long. At one end is welded a 14” long arm with a 3000psi cylinder(column load of 125000lb.) pushing or pulling the arm. It was supported in three basic areas, at both ends and the middle. Its snapped in-half. What forces had to act on the far end to snap it? Very interested in seeing the work, Show work.
