A simply supported wood beam with a span of L = 16 ft
supports a uniformly distributed load of w0 =
305 lb/ft. The allowable bending stress of the wood is 1.30 ksi. If
the aspect ratio of the solid rectangular wood beam is specified as
h/b = 1.75, calculate the minimum width
b that can be used for the beam.
