Question: A simply supported wood beam AB with span length L = 4m carries a uniform load of intensity q = 5.8kN/m (see figure). (a) Calculate

A simply supported wood beam AB with span length L = 4m carries a uniform load of intensity q = 5.8kN/m (see figure).
(a) Calculate the maximum bending stress Ïƒmax due to the load if the beam has a rectangular cross section with width b = 140mm and height h = 240 mm.

(b) Repeat (a) but use the trapezoidal distributed load shown in the figure part (b).
