An angle section with equal legs is subjected to a bending moment M having its vector directed along the 1–1 axis, as shown in the figure.

Determine the orientation of the neutral axis and calculate the maximum tensile stress

_t
and maximum compressive stress

_c
if the section is an L 200 200
 19 section and M = 4.5 kN. m. See Table F-4 of Appendix F for the dimensions and properties of the angle section.
