For Scantlings 17 inches deep, multiply the weights in this table 
by f|-|= 1-1289, and the deflections by 4-f=-941. 
For Scantlings 18 inches deep, multiply the weights in this table 
by 11= 1-2656, and the deflections by 1= -888. 
* Example.— '^^i. Pine 16 in. by 12 in., 28 feet long, with 109-71 cwts. uniformly loaded, 
(one-eighth the breaking weight) deflects -805 of an inch ; and with 109 71 cwts. suspended 
from the middle, (one-fourth the breaking weight) the deflection is 1-389 inches.
