"This chapter serves as a review of the stress analysis that has been developed in the previous chapters regarding axial load, torsion, bending and shear. We will discuss the solution of problems where several of these internal loads occur simultaneously on the member's cross section. Before doing this, however, the chapter begins with an analysis of stress developed in thin-walled pressure vessels."
