STRENGTH OF BEAM ACROSS A RECTANGLE AREA OF A LOG

A wooden beam has a rectangular cross section of height h in. and width w in. (see the accompanying figure). The strength S of the beam is directly proportional to its width and the square of its height. What are the dimensions of the cross section of the strongest beam that can be cut from a round log of diameter d = 29 in.? Hint: S = kh2w, where k is a constant of proportionality. (Round your answers to one decimal place.)
w =___in
h = ___in
