4) a) Calculate and draw the normal and tangential (shear) stress diagrams
b) For point A of the given cross sections calculate the principal stress and
maximum shear stress.
5) Check the strength for point A of given cross-section using the distortion ener-
gy failure theory (Huber - Hencky - von Mises theory) if $f_y$=250MPa
