A small dam of height h = 6ft is constructed of vertical wood beams , as shown in the figure. The wood beams AB, which have thickness t = 2.5in are simply supported by horizontal steel beams at A and B.
Construct a graph showing the maximum bending stress σmax in the wood beams versus the depth of the water above the lower support at B. Plot the stress σmax (psi) as the ordinate and the depth d (ft) as the abscissa.
