For Scantlings 3^^ inches deep, multiply the weights in this table 
by -ff = 1^3611, and the deflections by ^=-857.f 
* Example 1.— Red Pine 3 in. by 2k in., 3 feet long, with 6-75 cwts. uniformly loaded, 
(one-eighth the breaking weight) deflects "049 of an inch ; and with 6-75 cwts. suspended 
from the middle, (one-fourth the breaking weight) the deflection is "079 of an inch. 
f* Example 2.— Red Pine 3^ in. by 2^ in., 3 feet long, with 675 x 1-36 = 918 cwts. 
uniformly loaded, (one-eighth the breaking weight) deflects "049 x |. = -042 of an inch ; and 
with 9-18 cwts. suspended from the middle, (one-fourth the breaking weight) the deflection 
is -079 X 6 =-068 of an inch.
