Question

Two wood beams, each of rectangular cross
section (3.0 in. X 4.0 in., actual dimensions), are
glued together to form a solid beam with dimensions
6.0 in. X 4.0 in. (see figure). The beam is simply supported
with a span of 8 ft.
(a) What is the maximum moment Mmax that may
be applied at the left support if the allowable
shear stress in the glued joint is 200 psi? (Include
the effects of the beam’s own weight, assuming
that the wood weighs 35 lb/ft3.)
(b) Repeat part (a) if Mmax is based on allowable
bending stress of 2500 psi.
