For the part below, a$)$ calculate the forces and moments at the fixed wall cross section; b$)$ calculate the Denuing, torsional stresses at point A $(12$ o'clock position$)$; c$)$ create a stress element at point A $($neglect transverse shear stress$)$ and d$)$ calculate the principal stresses ${}_1$ and ${}_2$ and max shear stress at point $A.$ Document your answers in the tables provided.
