2.6 Draw the Mohr's stress circle for a bi-axial stress system having two direct stresses of 30 MPa (tensile) and 20 MPa (compressive). Determine the magnitude and the direction of the resultant stresses on planes which make angles of (i) 25°, and (ii) 70° with the 30 MPa stress. Also, find the normal and (For 25° plane: 21 MPa (tensile), 19 MPa; 28.5 MPa; 42°; For 70° plane: 14.2 MPa (comp.), 16 MPa; 21. MPa; 131.5°) shear stresses on these planes. 2.6 Draw the Mohr's stress circle for a bi-axial stress system having two direct stresses of 30 MPa (tensile) and 20 MPa (compressive).
