"In this chapter, we will develop a method for finding the shear stress in a beam having a prismatic cross section and made from homogeneous material that behaves in a linear-elastic manner. The method of analysis to be developed will be somewhat limited to special cases of cross-sectional geometry. Although this is the case, it has many wide-range applications in engineering design and analysis. The concept of shear flow, along with the shear stress, wil be discussed for beams and thin-walled members. The chapter ends with a discussion of the shear center."

LONGITUDINAL SHEAR-STRESS
A STRESS IN WHICH THE MATERIAL ON ONE SIDE OF A LONGITUDINAL BEAM PUSHES ON THE MATERIAL ON THE OTHER SIDE OF THE LONGITUDINAL BEAM WITH A FORCE PARALLEL TO THE SURFACE AND ACTING ALONG THE LONGITUDINAL PLANES OF THE BEAM.
