At a section in a beam the tensile stress due to bending is 70 N/mm2 and there is a shear stress of 25 N/mm2. Determine from first principles, the magnitude and direction of the principal stresses and calculate the max shear stress. Also show the results on a properly oriented elements in each cases.
