For Scantlings 13^ inches deep, multiply the weights in this table 
by -^1=1-0784, and the deflections by |^=^963.-f- 
* Example 1. — Red Pine 13 in. by 9 in., 13 feet long, with 117 cwts. uniformly loaded, 
(one-eighth the breaking weight) deflects 2]4i of an inch ; and with 117 cwts. suspended from 
the middle, (one-fourth the breaking weight) the deflection is '342 of an inch. 
t* Example 2.— Red Pine 13i in. by 9 in., 13 feet long, with 117 ^ 1 0784 = 126 17 
cwts. uniformly loaded, (one-eighth the breaking weight) deflects '214 x '963 = '206 of an 
inch ; and with 126'17 cwts. suspended from the middle, (one-fourth the breaking weight) 
the deflection is -342 x -963 = -329 of an inch.
