At a point in a stressed body, the cartesian components of stress are Oxx = 60 MPa, Guy = -40 MPa, Ozz = 20 MPa, Txy = -40 MPa, Tyz = 20 MPa, and Txz = 30 MPa. Determine: (a) The principle stresses and their direction cosines. (b) The normal and shear stresses on a plane whose outer normal has the following direction cosines: cos (n,x) = 0.429; cos (n, y) = 0.514; cos (n, z) = 0.743
