a) The principal stress components (01, 02 and o3) and their angles with respect to
the x-y-z axes of the planes where they are formed
calculate
b) Calculate the maximum shear stress (tmax) and the angles of the plane in which it
is formed with respect to the x-y-z axes.
c) Drawthe 2-D and 3-D Mohr circles for the stress components.
d) At point O in a section plane passing through point O and having an angle of 30°
