:* For Scantlings 4i inches deep, multiply the weights in this table 
by 1-2656, and the deflections by |-=-888,f 
* Example 1.— Red Pine 4 in. by 2^ in., 4 feet long, with 10 cwts. uniformly loaded, 
(one-eighth the breaking weight) deflects -066 of an inch ; and with 10 cwts. suspended from 
the middle, (one-fourth the breaking weight) the deflection is '105 of an inch. 
f * Example 2.— Red Pine 4^ in. by 2h in., 4 feet long, with 10 x 1-2656 = 12-656 cwts. 
uniformly loaded, (one-eighth the breaking weight) deflects -066 x 8.= -059 of an inch ; and 
with 12-656 cwts. suspended from the middle, (one-fourth the breaking weight) the deflection 
is-105x|. = -093 ofaninch.
