Question

A wood beam with a rectangular cross section
(see figure) is simply supported on a span of
length L. The longitudinal axis of the beam is horizontal,
and the cross section is tilted at an angle α.
The load on the beam is a vertical uniform load of
intensity q acting through the centroid C.
Determine the orientation of the neutral axis
and calculate the maximum tensile stress σmax if
b = 80 mm, h =140 mm, L =1.75 m, α = 22.58, and
q = 7.5 kN/m.
