*** For Scantlings 81 inches deep, multiply the weights in this table 
by M289, and the deflections by 4-f =-941.t 
* Example 1. — Red Pine 8 in. hy 4^ in., 8 feet long, with 36 cwts. uniformly loaded, 
(one-eighth the breaking weight) deflects '131 of an inch ; and with 86 cwts. suspended from 
the middle, (one-fourth the breaking weight) the deflection is "210 of an inch. 
t* Example 2.— Red Pine 8h in. by 4^ in., 8 feet long, with 36 x 1-1289 = 40-64 cwts. 
uniformly loaded, (one-eighth the breaking weight) deflects '131 x '941 = 123 of an inch; 
and with 40-64 cwts. suspended from the middle, (one-fourth the breaking weight) the 
deflection is -21 x -941 = -198 of au inch.
