* Example.— Kti Pine 12 feet long, 12-49 in. by 9 in., or 12-06 by 10, or 11-68 by 
11, or 11-35 by 12, or 11-05 by 13, or 10 78 by 14, or 10-53 by 15, wth 123;42 cwts. 
uniformly loaded, or 77-14 cwts. suspended from the middle, deflects of an inch. 
The breaking weight of Red Pine 12 feet long, 12-06 in. by 10 in., is 7-85 x 123-42 = 
968-8 cwts. uniformly loaded, or 6-38 x 77-14=484-4 cwts. suspended from the middle.
