*** For Scantlings 12i inches deep, multiply the weights in this table 
by 4fi= 1'08507, and the deflections by f|=-96.f 
* Example 1. — Red Pine 12 in. by 8 in., 8 feet long, with 144 cwts. uniformly loaded, 
[one-eighth the breaking weight) deflects "088 of an inch; and with 144 cwts. suspended 
;rom the middle, (one-fourth the breaking weight) the deflection is '140 of an inch. 
[ f* Example 2.— Red Pine 12| in. by 8 in., 8 feet long, with 144 x 1-085 = 156-25 cwts. 
aniformly loaded, (one-eighth the breaking weight) deflects '088 x '96 = -084 of an inch; and 
vith 156-25 cwts. suspended from the middle, (one-fourth the breaking weight) the deflection 
s -14 X -96 = -134 of an inch.
