For Scantlings 4i inches deep, multiply the weights in this table 
by 1-2656, and the deflections by|-=-888.t 
* Example 1.— Red Pine 4 in. by 2h in., 11 feet long, with 3-63 cwts uniformly loaded, 
(one-eighth the breaking weight) deflects -497 of an inch; and with 3-63 cwts. suspended from 
the middle, (one-fourth the breaking weight) the deflection is -795 of au inch. 
f * Example 3.— Red Pine 4>h in. by 2^ in., 11 feet long, with 3-63 x 1-2656 = 4*59 cwts. 
uniformly loaded, (one-eighth the breaking weight) deflects -497 x |-= '442 of an inch ; and 
with 4-59 cwts. suspended from the middle, (one-fourth the breaking weight) the deflection 
is -795 X 8 =-707 of an inch.
