At a point in a stressed body, the known stresses are σx= 14 ksi
(T), σy= 13 ksi (T), σz= 11 ksi (T), τxy= 5 ksi, τyz= -3 ksi, and
τzx= 0. Determine (a) the normal and shear stresses on a plane
whose outward normal is oriented at angles of 37°, 59°, and 71.86°
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.
Part 1 At a point in a stressed body, the known stresses are 0x = 14 ksi (T), y = 13 ksi (T), z = 11 ksi (T), Txy = 5 ksi, Tyz = -3 ksi, and Ty = 0. Determine (a) the normal and shear stresses on a plane whose outward normal is oriented at angles of 379,590, and 71.86° 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.
