*#* For Scantlings 8 J inches deep, multiply the weights in this table 
by 1-1289, and the deflections by ^=-Ml.f 
* Example 1. — Bed Pine 8 in. by 4i iu., 24 feet lon^, with 12 cwts. uniformly loaded, 
(oue-eiorhth the breaking weight) deflects 1-183 inches; and with 12 cwts. suspended from 
the middle, (one-fourth the breaking weight) the deflection is 1-893 inches. 
f * Example 2.— Red Pine 8^ in. by 4^ jii., 24 feet long, with 12 x 1-1289 = 13-54 cwts. 
uniformly loaded, (one-eighth the breaking weight) deflects 1-183 x -941 = 1-113 inches; and 
with 13-54 cwts. suspended from the middle, (oue-fourth the breaking weight) the deflectioa 
is 1-893 X -941 = 1-781 inches.
