2.3 The stresses on two perpendicular planes through a point are 120 MPa tensile, 80 MPa compression and 60 MPa shear. Determine the normal and shear stress components on a plane at 60° to that of the 120 MPa stress and also the resultant and its inclination with the normal component on the plane. (22 MPa; 116.5 MPa; 118.6 MPa; 79.3°) 2.3 The stresses on two perpendicular planes through a point are 120 MPa tensile, 80 MPa compression and 60 MPa shear.
