For Scantlings 13| inches deep, multiply the weights in this table 
by ^= 1-0784, and the deflections by ^^=-963. f 
* Example 1. — Red Pine 13 in. by 9 in., 5 feet long, with 304-20 cwts. uniformly loaded, 
(one-eighth the breaking weight) deflects -032 of an inch; and with 304'20 cw^s. suspended 
from the middle, (one-fourth the breaking weight) the deflection is -051 of an inch. 
f * Example 2.— Red Pine 13^ in. by 9 in., 5 feet long, with 304-2 x 1-0784 = 328 05 
cwts. uniformly loaded, (one-eighth the breaking weight) deflects -032 x '963 = -031 ofau 
inch; and with 328-05 cwts. suspended from the middle, (one-fourth the breaking weight) 
the deflection is -051 x -963 = -049 of an inch.
