Consider a beam of rectangular crosssection subjected to both axial force P and moment M. The Method of Superposition is used to determine the normal stresses on the beam's crosssection. Click below to see the normal stress distribution due to: 

Consider a beam of circular crosssection subjected simultaneously to both shear force V and torque T. The Method of Superposition is used to determine the shear stresses on the beam's crosssection. Click below to see the Shear Stresses at points 0, 1, 2, 3, and 4 due to: Note: the crosssection shown is viewed along the negative x direction.
