*** For Scantlings 15^ inches deep, multiply the weights in this table 
by 11^=1*0677, and the deflections by |5^=*968.t 
• Example 1. — Red Pine 15 in. by 11 in., 27 feet long, with 91-66 cwts. uniformly loaded, 
(one-eighth the breaking weight) deflects -799 of an inch ; and with 91-66 cwts. suspended 
from the middle, (one-fourth the breaking weight) the deflection is 1-278 inches. 
f * Example 2.— Red Pine 15i in. by 11 in., 27 feet long, with 91-66 x 1-0677 = 97-87 
cwts. miiformly loaded, (one-eighth the breaking weight) deflects '799 x '968 = -773 of an 
inch ; and with 97-87 cwts. suspended from the middle, (one-fourth the breaking weight) the 
deflection is 1278 x -968 = 1-237 inches.
