For Scantlings 17 inches deep, multiply the weights in this table 
by 141=1-1289, and the deflections by ^■=-M\. 
For Scantlings 18 inches deep, multiply the weights in this table 
by 1-2656, and the deflections by |=-888. 
* Example. — Eed Pine 16 in. by 12 in., 8 feet long, with 384 cwts. uniformly loaded, 
(one-eighth the breaking weight) deflects "066 of an inch; and with 384 cwts. suspended from 
the middle, (one-fourth the breaking weight) the deflection is -105 of an inch.
