The redundant shear flow in a closed section is found by imposing

  • A.A second equilibrium equation
  • B.The condition that stress is uniform
  • C.The condition that the section is symmetric
  • D.A compatibility condition on the twist

Answer: D

Equilibrium alone cannot fix the constant, so a deformation condition is added: for a load through the shear centre the twist is zero, and for pure torsion the rate of twist is the same for every cell. That extra equation closes the problem.
