At a point in a stressed body, the known stresses are o, = 15 ksi (T). o, 12 ksi (T). oz = 11 ksi (T). Try = 3 ksi, Tyz = -4 ksi, %3D and = 0. Determine (a) the normal and shear stresses on a plane whose outward normal is oriented at angles of 41°, 61°, and 63.77° with the x, y, and z axes, respectively. (b) the principal stresses and the absolute maximum shear stress at the point. Determine the three orthogonal components of the resultant stress. Answers:
