Shafts Subjected to Combined Twisting Moment and Bending Moment
Various theories have been suggested to account for the elastic failure of the materials when they are subjected to various types of combined stresses.
The following two theories are important from the subject point of view : 1. Maximum shear stress theory or Guest's theory. It is
used for ductile materials such as mild steel. 2. Maximum normal stress theory or Rankine’s theory. It is
used for brittle materials such as cast iron.
