Moment calculation!! Can anyone HELP me with this?!!?

Question

HI guys, I have the diagram in the link below, and I was wondering how would I do the following calculations?! In the figure shown, would there be any other stresses other than bending stress due to moment? I know there would be shear, but how would I calculate that? Also in the position (12-6 o'clock) there wold be no torsion, right?

Answer 1

L2 is the momenat arm.

There will be torsion only if F does not coincide with the facial axis of L2.
