*#* For Scantlings 12^ inches deep, multiply the weights in this table 
by ff^= 1-08507, and the deflections by |4=-96.t 
• Example 1. — Red Pine 12 in. by 8 in., 12 feet long, with 96 cwts. uniformly loaded, 
(one-eighth the breaking weight) deflects "197 of an inch ; and with 96 cwts. suspended 
from the middle, (one-fourth the breaking weight) the deflection is '316 of an inch. 
f* Example 2.— Red Pine 12^ in. by 8 in., 12 feet long, with 96 x 1-085 = 104-16 cwts. 
uuifortnly loaded, (one-eighth the breaking weight) deflects -197 x -96 = '189 of auiuch; and 
with 104-16 cwts. suspended from the middle, (one-fourth the breaking weight) the deflection 
is -316 X -96 = -303 of an inch.
