The components of the traction at a given plane is given by j ji j ij n i n n T ) ( or T n n , (2.1) where ij represent the symmetric stress tensor and j n represents the outward normal unit vector of the plane under consideration. (a)i. State of stress: ij unit vector normal to the plane: 2 1 2 1 j n After substituting the known values into Equation (2.1), we obtained the traction on the plane under consideration 2 2 2 2 2 1 2 1 n T or 2 1 2 2 e e T n ii. 2 2 2 2 2 1 2 1 n T or 2 1 2 2 e e T n (b)i. State of stress: ij the plane under consideration is the same as in (a)....
