*.){.* For Scantlings 6^ inches deep, multiply the weights in this table 
by -fff =M736, and the deflections by 4.f = -923.f 
* Example 1. — Red Pine 6 in. by 3t in., 12 feet long, with lO'SO cwts. uniformly loaded, 
(one-eighth the breaking weight) deflects -394 of an inch ; and with 10-50 cwts. suspended 
from the middle, (one-fuurth the breaking weight) the deflection is -631 of an inch. 
f * Example 2.— Red Pine 6Uu. by 3^ in., 12 feet long, with 10 b x 1-1736 = 12-32 cwts. 
uniformly loaded, (one-eighth the breaking weight) deflects '394 x _i 2. = .363 of an inch; and 
with 12-32 cwts. suspended from the middle, (one-fourth the breaking weight) the deflection 
is -631 X ^.| = -582 of an inch.
