The stresses on two perpendicular planes through a point in a body are 30 Mpa and 15 Mpa both tensile along with shear stress of 25 Mpa. Find by using Mohr's circle 1. The magnitude and direction of principal stresses 2. The plane of maximum shear stress 3. The normal and shear stress on the plane of maximum shearing stress 4. Draw stress element Original stress element, principal stress element and maximum shear stress element
