Halving the wall thickness of an open section changes its torsion constant by a factor of

  • A.One eighth
  • B.One half
  • C.One quarter
  • D.One sixteenth

Answer: A

The St Venant torsion constant carries the cube on the thickness, so halving it divides the stiffness by \( 2^3 = 8 \). Contrast the closed-section case, where the stiffness depends on thickness only to the first power.
