* Example. — Red Pine 5 feet long, 8-24 in. by 9 in., or 7-95 by 10, or Y'Tl 
by 11, or 7-48 by 12, or 7-29 by 13, or 7-11 by 14, or 6-95 by 15, 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, 7-95 in. by 10 in., is 7-85 x 128-92 
= 1012 cwts. uniformly loaded, or 6'23 x 80-58 = 506 cwts. suspended from the 
middle.
