Here, you can easily see that now the beam cross sections remain perpendicular to the neutral plane of the beam as the beam deflects. CONCLUSION: Shear stresses play an important role in the ...

The transverse load P will produce a shear force V in the positive y direction on a mathematical cut through the beam at point “a”. This shear force is directly responsible for the shear stress τ on ...

This video is an introduction to shear force and bending moment diagrams. What are Shear Forces ... the internal forces that develop within a beam when external loads are acting on it.
