*** For Scantlings 9 J inches deep, multiply the weights in this table 
by |4^= 1-1142, and the deflections by 4|=-947.t 
* Example 1. — Red Pine 9 in. by 9^ in., 17 feet long, with 45-26 cwts. uniformly- 
loaded, (one-eighth the breaking weight) deflects -528 of an inch ; and with 45-26 cwts. sus- 
pended from the middle, (one-fourth the breaking weight) the deflection is -844 of an inch. 
f* Example 2.— Red Pine 9i in. by 9^ in., 1? feet long, with 45-26 x 1-1142 = 50-43 
cwts. uniformly loaded, (one-eighth the breaking weight) deflects -528 x -947 = '500 of an 
inch ; and with 50-42 cwts. suspended from the middle, (one-fourth the breaking weight) 
the deflection is -844 x -947 = "799 of an inch.
