For Scantlings lOi inches deep, multiply the weights in this table 
by ^4^= 1-1025, and the deflections by f ° — -952.t 
* Example 1.— lied Pine 10 in. by 6 in., 10 feet long, with 60 cwts. uniformly loaded, 
(one-eighth the breaking weight) deflects "164 of an inch ; and with 60 cwts. suspended from 
the middle, (one-fourth the breaking weight) the deflection is '263 of an inch. 
f* Example 2.— Red Pine 10.i in. by 6 in., 10 feet long, with -60 x 1-1025 = 66-15 cwts. 
uniformly loaded, (one-eighth the breaking weight) deflects -164 x •952 = -156 of an inch; and 
with 66-15 cwts. suspended from the middle, (one-fourth the breaking weight) the deflection 
is -263 X -952 = -250 of an inch.
