Learning Goal:
To determine the absolute maximum bending stress in a rectangular cross section that has a circular cutout and is subjected to unsymmetrical bending in the y- and z-directional planes, and to determine the
angles of the neutral axes established by the applied moments.
The rectangular cross section ABCD shown below has a circular cutout of diameter d = 50.0 mm through its center. The member is subjected to two externally applied moments M₁ = = 6.0 kN. m
·m and M₂ = 17.0
kNm at angles 0₁ = 35.0 degrees from the y axis in the yz plane and 02 = 25.0 degrees from the z axis in the yz plane, respectively. The rectangular cross section has a height of h = 230.0 mm and a width of
w = 125.0 mm .
