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.

A simply supported wood beam with a span of L = 23 ft
supports a uniformly distributed load of w0 =
300 lb/ft. The allowable bending stress of the wood is 1.95 ksi. If
the aspect ratio of the solid rectangular wood beam is specified as
h/b = 2.25, calculate the minimum width
b that can be used for the beam.

A cantilever wood beam with a span of L = 21 ft
supports a linearly distributed load with maximum intensity of
w0 = 250 lb/ft. The allowable bending stress of
the wood is 1.70 ksi. If the aspect ratio of the solid rectangular
cross section is specified as h/b = 0.50,
determine the minimum width b that can be used for the
beam.

A simply supported wood beam with a span of L = 17 ft supports a uniformly distributed load of w0 = 250 lb/ft. The allowable bending stress of the wood is 1.65 ksi. If the aspect ratio of the solid rectangular wood beam is specified as h/b = 2.25, calculate the minimum width b that can be used for the beam.
A simply supported wood beam with a span of L = 12 ft supports a uniformly distributed load of w0 = 300 lb/ft. The allowable bending stress of the wood is 1.70 ksi. If the aspect ratio of the solid rectangular wood beam is specified as h/b = 3.00, calculate the minimum width b that can be used for the beam.

A simply supported composite beam 3 m long carries a uniformly distributed load of intensity q= 30 kN/m (see figure). The beam is constructed of a wood member, 100 mm wide by 150 mm deep, and is reinforced on its lower side by a steel plate 8 mm thick and 100 mm wide. (a) Find the maximum bending stresses σw and σs, in the wood and steel, respectively, due to the uniform load if the moduli of elasticity are Ew =...
