Even a piece of A36 1 1/2” steel rod should easily hold 35 to 50 ksi
Hard to believe it put anywhere near that amount of force on it as a bending moment
That is not bending,,
the rod is acting as a column,, totally different.
The column length (height) is the rod PLUS the length of the remainder of the cylinder.
That ends up being a VERY long column.
It is kinda like putting a 4 foot pipe on your 3/8" ratchet,,
DANG, the stupid rachet broke!!!
backing up with the bucket pointed down, creates a tremendous mechanical advantage.
If the cylinders had only been extended half as long, the column height would have been half,,
The cylinders would have survived.
