Understanding Stresses in Beams - YouTube

WebUniversity of Washington WebBending can induce both a normal stress and a transverse shear stress. The existence of this shear stress can be seen as cards slide past each other slightly when you bend a deck of cards. The magnitude of the shear stress becomes important when designing beams in bending that are thick or short – beams can and will fail in shear while bending.
