To Show How This Stress Can Develop, Considerthe Effect of Applying a Force FTO the Bar Infig.1 – 19a. ifthe Supports Are Considered Rigid, and Fislarge Enough, IT Will Cause The Material of the Barto Deform and Fail Along the Planes Identified By Aband CD. Afree - Body Diagram of the Unsupported Center Segm Entof the Bar, fig.1 – 19b, indicates the shear force v=f> 2 must be applied at each section to hold the segment in equilibriumAverage Shear Stress Distributed Over Each Sectioned Areathat Develops This Shear Force IsDefined By
