Mr Muffin,
Thank you.
1. Good idea and it's exactly what I'd try if it weren't for the torsion member being short - table 22 in Roark does not apply in this situation since "transverse shear deformations of the beam action are neglected" (p365 6ed). Do you know how to correct for...
Thanks so much for kicking this off Chris, this is my first posting and to receive help so quickly is really heartening.
It is two C shapes. When I said "stress it" I only meant to refer to the process of analysing it. It is only subjected to torque. I don't know dimensions and loads...
Firstly imagine a short circular hollow shaft, then split it in two on a plane passing through its axis. Now constrain the ends (not the cut faces) so that they cannot warp out of their initial plane. Now apply torque about axis. Now stress it.
This is much trickier than I imagined. Any...
