The unequal-leg angle is subjected to a bending moment of Mz = 14 kip-in. that acts at the orientation shown. The dimensions shown for the cross-section are b = 3.125 in., h = 4.250 in., and t = 0.375 in. The cross-section has a rectangular upright leg (1) of dimensions t x h, and a rectangular bottom leg (2) of dimensions (b-t) x t. Determine: (a) the bending stress at point H. (b) the bending stress at point K.

The unequal-leg angle is subjected to a bending moment of Mz = 14 kip-in. that acts at the orientation shown. The dimensions shown for the cross-section are b = 3.125 in., h = 4.250 in., and t = 0.375 in. The cross-section has a rectangular upright leg (1) of dimensions t x h, and a rectangular bottom leg (2) of dimensions (b-t) x t.
Determine:
(a) the bending stress at point H.
(b) the bending stress at point K.
(c) the orientation of the neutral axis relative to the +z axis. Show its location on a sketch of the cross section.
