Draw the internal shear and bending stresses at section A-A. c. Find the force couple equivalent to the bending stresses at section A-A. d. Find the principal stresses at Point 1 in the beam. Point 1 is located half-way between the neutral axis and the bottom fiber of the beam. Include a sketch of the beam element and its stresses, and the transformed beam element with its principal stresses. Note: Ok to assume an average shear stress distribution of T = A 1 ( 1.

draw the shear and moment diagram. show the complete computation. thank you.
