Question
A hollow box beam is constructed with webs
of Douglas-fir plywood and flanges of pine, as shown
in the figure in a cross-sectional view. The plywood is
1 in. thick and 12 in. wide; the flanges are 2 in. × 4 in.
(nominal size). The modulus of elasticity for the plywood
is 1,800,000 psi and for the pine is 1,400,000 psi.
(a) If the allowable stresses are 2000 psi for the plywood
and 1750 psi for the pine, find the allowable
bending moment Mmax when the beam is
bent about the z axis.
(b) Repeat part (a) if the beam is now bent about its
y axis.
