The torsion constant is a geometrical property of a bar's cross-section which is involved in the relationship between angle of twist and applied torque along the

ABSTRACT: Determining the torsion constants of all but a few cross-sec- by mapping the surface of the membrane stretched over the cross-section.
This Lecture continues the treatment of Thin Wall (TW) sections in torsion. We proceed say, 20% of the smallest cross section dimension. 2 Since q is constant along the contour, plainly the maximum shear stress occurs when the thickness.
a) Each cross-section ( each z) rotates as a rigid body (No. “distortion” of cross-section shape in x, y) b) Rate of twist, k = constant c) Cross-sections are free to
