On any plane (with unit outward normal) , the traction vector may be evaluated from the stress tensor as t = on. Once we have evaluated t, we can project it along n to obtain the normal stress component on = n tn. Then, we can evaluate the shear components of the traction from oss = tn - onn where s is a unit vector along the direction of the shear traction vector oss. Given [o] = = 7 0 3 0 -4 0 3 0 5 and [n] evaluate 1. the traction vector t 2. the normal stress component on, 3. the shear traction vector S, 4. and the magnitude os of the shear traction vector oss. = 2 0 2
