* Example.— Rei Pine 14 feet long, 9-73 in. by 6 in., or 9-24 by 7, or 8-84 by 8, 
or 8-50 by 9, or 8-20 by 10, or 7-95 by 11, or 7-72 by 12, with 42-87 cwts. uniformly 
loaded, or 26-79 cwts. suspended from the middle, deflects of an inch. 
The breaking weight of Red Pine 14 ft. long, 8 84 in. by 8 in., is 8-329 x 42-87 = 357 
cwts. uniformly loaded, or 6-663 x 26-79 = 178-5 cwts. suspended from the middle.
