At a point in a stressed body, the principal stresses are 100 MN/m2 (tensile) and 60 MN/m2 (compressive). Determine the normal stress and the shear stress on a plane inclined at 50degree counter clockwise to the axis of minor principal stress. Also, calculate the maximum shear stress at the point and draw the Mohr’s stress circle to verify the answers. If the yield strength and Poisson’s ratio of the material in the above case is 240 MPa and 0.3 respectively,...
