* Example.— Rei Pine 10 feet long, 12-14 in. by 9 in., or 11-73 by 10, or 11-36 by 
11, or 11-03 by 12, or 10-74 by 13, or 10-48 by 14, or 10-24 by 15, with 140 cwts. 
nniformly loaded, or 87' 50 cwts. suspended from the middle, deflects ^° of an inch. 
The breaking weight of Red Pine 14 feet long, 15-04 in. by 13 in., is 8-568 x 196 = 
1679-3 cwts. uniformly loaded, or 6-854 x 122-5 = 839-6 cwts. suspended from the 
middle.
