Which of the following is NOT true of the shear centre?

  • A.A load through it produces no twist
  • B.It lies on any axis of symmetry
  • C.It coincides with the centroid for a doubly symmetric section
  • D.It always lies within the material of the section

Answer: D

Correct answer: It always lies within the material of the section

The shear centre is a geometric property and can lie well outside the material. For a channel it sits on the far side of the web from the flanges, in the air; for an angle it lies at the intersection of the two legs. This is exactly why a channel twists so readily under a load applied at its web.
