For Scantlings 10^ inches deep, multiply the weights in this table 
by m= 1-1025, and the deflections by f?^=-952.f 
* Example 1. — Red Pine 10 in. by 6 in., 6 feet long, with 100 cwts. uniformly loaded, 
(one-eighth the breaking weight) deflects '059 of an inch ; and with 100 cwts. suspended from 
the middle, (one-fourth the breaking weight) the deflection is '095 of an inch. 
f* Example 2.— Red Pine \0k in. by 6 iu., 6 feet long, with 100 x 1-1025 = 110-25 cwts. 
uniformly loaded, (one-eighth the breaking weight) deflects '059 x '952 = '056 of an inch ; and 
with 110-25 cwts. suspended from the middle, (one-fourth the breaking weight) the deflection 
is 095 X -952 = -090 of an inch.
