Problem definition
A beam of channel section is subject to a
bending moment M having its vector at
angle theta to the z-axis as shown in the
figure. Determine the orientation of the
neutral axis and then determine the
maximum tensile and compressive
stresses. Assume that the following
information is provided: M= 0.75 kN; q=
20o; Iz =15x106 mm4; Iy = 0.663x106 mm4;
d=203 mm; b= 59.4 mm; c=14.1 mm
