Shear Stresses

Picture
•Transverse loading applied to a beam results in normal and shearing stresses in transverse sections.



•Distribution of normal and shearing stresses satisfies

Picture
•When shearing stresses are exerted on the vertical faces of an element, equal stresses must be exerted on the horizontal faces•Longitudinal shearing stresses must exist in any member subjected to transverse loading.
•Consider prismatic beam•For equilibrium of beam element
•For of  beam element
