For Scantlings 10| inches deep, multiply the weights in this table 
by ^=1-1025, and the deflections by |4=-952.f . 
* Example 1. — Red Pine 10 in. by 6 in., 18 feet long, with 33-33 cwts. uniformly loaded, 
(one-eighth the breaking weight) deflects "532 of an inch; and with 33-33 cwts. suspended 
from the middle, (one-fourth the breaking weight) the deflection is -852 of an inch. 
f* Example 2.— Red Pine lOi in. by 6 in., 18 feet long, with 33'83 x 1-1025 = 36-75 
cwts. uniformly loaded, (one-eighth the breaking weight) deflects '532 x -952 = '506 of an inch; 
and with 36"75 cwts. suspended from the middle, (one-fourth the breaking weight) the deflec- 
< ion is -852 X -952 = -811 of an inch.
