* Example.— -Rei Pine 12 ft. long, 1573 in. by 4^ in., or 1519 by 5, or 14-29 
by 6, or 13-58 by 7, or 12-99 by 8, with 123-42 cwts. uniformly loaded, or 
77'14 cwts. suspended from the middle, deflects of an inch. 
The breaking weight of Red Pine 12 ft. long, 13-58 in. by 7 in. is 6-97 x 123-42 = 860-2 
cwts. uniformly loaded, or 5-576 x 77'14 = 430.1 cwts. suspended from the middle.
