* Example.— Red Pine 9 feet long, ll ^l in. by 9 in., or 11-30 by 10, or 10 95 by 
11, or 10-64 by 12, or 10-36 by 13, or 1010 by 14, or 9-87 by 15, with 144 64 cwts. 
uniformly loaded, or 90-40 cwts. suspended from the middle, deflects of an inch. 
The breaking weight of Red Pine 11 ft. long, 13-00 in. by 12 in., is 8-343 x 176-78 
= 1474-8 cwts. uniformly loaded, or 6-674 x 110-49 = 737-4 cwts. suspended from the 
middle.
