Under torsion only, the shear stress is minimum, in fact zero, at the center point ( where radius is zero)
I need to calculate the stress resulting from a torsion moment on a hollow steel section as well as a flat plate.
Yes.Modulus of RuptureUltimate strength determined in a flexure or torsion test. In a flexure test, modulus of rupture in bending is the maximum fiber stress at failure. In a torsion test, modulus of rupture in torsion is the maximum shear stress in the extreme fiber of a circular member at failure. Alternate terms are flexural strength and torsional strength.
It is torsion and tension while tightening, and pure tension when tightened

ROD is used for axial loading and torsion, but BAR can be used for axial, torsion as well as bending loads....

"Small Wonder, the Amazing Story of the Volkswagen" by Walter Henry Nelson (paperback) states on page 31 states that Ferdinand Porsche developed and patented the torsion bar. It became public property after 1950.
Torsion
A torsion bar is used in an auto suspension. A torsion bar suspension, also known as a torsion spring suspension or torsion beam suspension, is a general term for any vehicle suspension that uses a torsion bar as its main weight bearing spring. One end of a long metal bar is attached firmly to the vehicle chassis; the opposite end terminates in a lever, the torsion key, mounted perpendicular to the bar, that is attached to a suspension arm, a spindle, or the axle. Vertical motion of the wheel causes the bar to twist around its axis and is resisted by the bar's torsion resistance. The effective spring rate of the bar is determined by its length, cross section, shape, material, and manufacturing process.
Torsion means twisting or being twisted. Intestinal torsion can be fatal.
torsion
Torsion strength measures the largest torsion force the material can withstand and still spring back into its original shape.
Vehicle does not have torsion bars
Instead of using coil springs on the front suspension torsion bars are used from the lower control arms to the frame ( my 1995 Ford Explorer 4x4 has torsion bars , my dads 73 Dodge Coronet had torsion bars ) If you look at a lower front suspension that has torsion bars you will see the torsion bars going from the lower control arms rearward
