* Example.— R^i Pine, 5 feet long, 13-60 in. by 2 in., or 12-63 by 2h, or 11-88 
by 3, or 11-29 by 3i, or 10-80 by 4, or 10-38 by 4i, or 10-02 by 5, or 9-43 by 6, or 
8-96 by 7, or 8-57 by 8, with 128 92 cwts. uniformly loaded, or 80-58 cwts. 
suspended from the middle, deflects -Jj of an inch. 
The breaking weight of Red Pine 5 feet long, 12-63 in. by 2i in., is 4-945 x 128-92 
= 637-5 cwts. uniformly loaded, or 3-956 x 80 58 = 3187 cwts. suspended from the 
middle.
