* Example. — Red Pine 5 feet long, 1-97 in. by H in., or 1-87 by If, or 1^79 by 2, 
or 1-72 by 2^ or 1-66 by 2^ or 1-56 by 3, or 1-49 by 3^, with -69 cwts. uniformly 
loaded, or '43 cwts. suspended from the middle, deflects J-^ of an inch. 
The breaMng weight of Red Pine 5 ft. long, 1-79 in. by 2 in., is 14-69 x '69 = lO'l cwts. 
uniformly loaded, or 11-75 x -43 = 5'0 cwts. suspended from the middle. The breaking 
weight of Red Pine 6 feet long, 2'15 in, by 2 in., is 14"69 x -83 = 12-2 cwts, uniformly 
loaded, or 11-75 x -53 = 6-1 cwts. suspended from the middle, and so on, throughout the 
table.
