* Example. — The greatest weight, uniformly loaded, upon a Red Pine beam 15 inches 
deep and 25 feet long, is, including always the weight of the beam, 10 cwts. to the foot; 
then if 4 times that weight be the breaking weight to the foot, the breadth of the beam should 
be 4 X 10 X •3472 = 13-89 inches. 
By Table II. page 131, the deflection of a Red Pine beam 15 inches deep and 25 feet long, 
uniformly loaded with one-fourth of Ihe breaking weight, is 1-37 inches.
