* Example.— RqA Pine 15 feet long, 11-17 in. hy 6 in., or 10-61 by 7, or 10-15 by 
8, or 9-75 by 9, or 9-42 by 10, or 913 by 11, or 8-86 by 12, witli 56-50 cwts. uniformly 
loaded, or 35-31 cwts. suspended from the middle, deflects of an inch. 
The breaking weight of Red Pine 15 feet long, 9-75 in. by 9 in., is 8-084 x 56-5 = 
456-7 cwts. uniformly loaded, or 6-467 x 35-31 = 228-3 cwts. suspeuded from the middle.
