* Example.— Red. Pine 8 feet long, 11-10 in. by 9 in., or lO'TS by 10, or 10-38 
by 11, or 10-09 by 12, or 9-82 by 13, or 9-58 by 14, or 9-36 by 15, with 146-28 
cwts. uniformly loaded, or 91-42 cwts. suspended from the middle, deflects of au 
inch. 
The breaking weight of Red Pine 10 ft. long, 12-98 in. by 11 in., is 8-105 x 182-85 = 
1483 cwts. uniformly loaded, or 6-484 x 114-28 = 741 cwts. suspended from the mid^e.
