For Scantlings 15J inches deep, multiply the weights in this table 
by 1-0677, and the deflections by |° = -968.t 
* Example 1. — Red Pine 15 iu. by 11 in., 7 feet long, with 353-57 cwts. uniformly loaded, 
(one-eighth the breaking weight) deflects -054 of an inch ; and with 353-43 cwts. suspended 
from the middle, (one-fourth the breaking weight) the deflection is -086 of an inch. 
f* Example 2.— Red Pine 15Hn. by 11 in., 7 feet long, with 353-57 x l-0677 = 377-53 
cwts. uniformly loaded, (one-eighth the breaking weight) deflects -054 x -968 = -052 of an 
inch ; and with 377'53 cwts. suspended from the middle, (one-fourth the breaking weight) the 
deflection is -086 x -968 = -083 of an inch.
