*#* For Scantlings 17 inches deep, multiply the weights in this table 
by f||=M289, and the deflections by ^^=-941. 
For Scantlings 18 inches deep, multiply the weights in this table 
by |i= 1-2656, and the deflections by |-=.888. 
* Example. — Red Pine 16 in. by 12 in., 16 feet long, with 192 cwts. uniformly loaded, 
(one-eighth the breaking weight) deflects -263 of an inch ; and with 192 cwts. suspended from 
the middle, (one-fourth the breaking weight) the deflection is -421 of an inch.
