*** For Scantlings 13^ inches deep, multiply the weights in th] 
by 7-1^1= 1-0784, and the deflections by f f—.ggs 
s table 
* Example 1. — Red Pine 13 in. by 9 in., 25 feet long, with 60-84 cwts. uniformly loaded, 
(oBe-eighth the hreaMng weight) deflects -790 of an inch ; and with 60"84 cwts. suspended 
from the middle, (one-fourth the breaking weight) the deflection is 1-264 inches. 
f * Example 2.— Red Pine 13^ in. by 9 in., 25 feet long, with 60-84 x 1-0784 = 65-61 
cwts. uniformly loaded, (otie-eighth the breaking weight) deflects -79 x -963 = -761 of au 
nch ; and with 65-61 cwts. suspended from the middle, (one-fourth the breaking weight) the- 
deflection is 1-264 x -963 = 1-217 inches.
