A cantilever timber beam with a span of L = 2.2 m supports a uniformly distributed load w. The beam width is b = 300 mm and the beam height is h = 200 mm. The allowable bending stress of the wood is 7.7 MPa. Determine the magnitude of the maximum load w that may be carried by the beam. L Answer: w= i b kN/m.

A person by the name of Huebscher developed a relationship between theequivalent size of round ducts and rectangular ducts according to                  D = diameter of equivalent circular duct (mm)a = dimension of one side of the rectangular duct (mm)b = the other dimension of the rectangular duct (mm)Using Excel, create a table that shows the relationship between the circular and the rectangular duct dimensions, similar to the one shown in the accompanying table.
