Question

What factors change the torsion constant ?

Answer 1

Explanation:

Hi

d(torsion angle) / d(length) =cte

thus:

torsion angle / total length = constant.

in the length: arc length = shear strain* d(length) (1)

in the length: arc length = radius*torsion angle (2)

1 = 2 results torsion angle = T*L/(G*J) according to shearing strain = shearing stress / G.
