Question

Consider a long slender beam, clamped at its left edge and subject to a uniform/constant downward traction t ? on its top surface as depicted below.

Consider the case in which you are applying a (virtual) horizontal cut along the red dashed line in order to consider the top section of the beam that’s established by applying the cut. Determine all the stress components that could be acting on the bottom surface of this section based on the engineering convention for stress components (i.e. do not conduct a qualitative stress analysis; you are only asked to state which stresses could be acting on the bottom surface). Provide a drawing in which you show the stresses in their positive definition. Explain your answer.

Explanation / Answer

As the section is cut along the horizontal axis shear stress will be developed.
