For Scantlings 7^ inches deep, multiply the weights in this table 
by 4f^= 1-148, and the deflections by i-f=-933.t 
* Example 1.— Eed Pine in- by 4 in., 14 feet long, with 14 cwts. uniformly loaded, 
(one-eighth the breaking weight) deflects -460 of an inch; and with 14 cwts. suspended from 
the middle, (one-fourth the breaking weight) the deflection is -736 of an inch. 
f* Example 2.— Red Pine, in. by 4 in., 14 feet long, with 14 x 1-148 = 16-07 cwts. 
uniformly loaded, (one-eighth the breaking weight) deflects "46 x -933 = 429 of an inch ; and 
with 16-07 cwts. suspended from the middle, (one-fourth the breaking weight) the deflection 
is -736 X -933 = -687 of an inch.
