*»* For Scantlings 9^ inches deep, multiply the weights in this table 
by |4^= 1-1142, and the deflections by f|=-947.t 
* Example 1. — Red Pine 9 in. by 5 in., 9 feet long, with 45 cwts. uniformly loaded, 
(one-eighth the breaking weight) deflects -148 of an inch ; and with 45 cwts. suspended from 
the middle, (one-fourth the breaJdng weight) the deflection is -237 of an inch. 
f* Example 2.— Red Pine 9i in. by 5 in., 9 feet long, with 45 x 1-1142 = 50-13 cwts. 
uniformly loaded, (one-eighth the breaking weight) deflects -148 x -947 = "140 of an inch ; 
and with 5013 cwts. suspended from the middle, (one-fourth the breaking weiglit) the 
deflection is -237 x "947 = -224 of an inch.
