In this chapter we shall consider the Saint Venant theory of torsion for uniform prismatic elastic rods loaded by twisting couples at the ends of the rod (see Fig. 5.1). You will recall that for the special case of a circular cross section, it is assumed in strength of materials (and shown valid in the theory of elasticity) that cross sections of the rod merely rotate as rigid surfaces under the action of the twisting couples.
