* Example.— K^d. Pine 13 feet long, 15-62 in. by 4^ in., or 15-08 by 5, or 
14-20 by 6, or 13-48 by 7, or 12-90 by 8, with 112-35 cwts. uniformly 
loaded, or 70-22 cwts. suspended from the middle, deflects of an inch. 
The breaking weight of Red Pine 13 feet long, 12-90 in. by 8 in., is 7-288 x 112-35 = 
818-8 cwts. uniformly loaded, or 5-83 x 70-22 = 409-4 cwts. suspended from the middle.
