For Scantlings 7i inches deep, multiply the weights in this table 
by 1-148, and the deflections by 44=-933.f 
* Example 1.— Red Pine 7 in. by 4 in., 21 feet long, with 9-33 cwts. uniformly loaded, 
(one-eighth the breaking weight) deflects 1-085 inciies; and with 9-33 cwts. suspended from 
the middle, (one-fom-th the breaking weight) the deflection is 1-657 inches. 
t* Example 2.— Red Pine 7k in. by 4 in., 21 feet long, with 9-33 x 1-148 = 10-71 
cwts. uuifoi-mly loaded, (one-eighth the breaking weight) deflects 1-035 x -933 = -966 of an 
inch ; and with 10-71 cwts. suspended from the middle, (one-fourth the breaking weight) the 
deflection is 1-657 X -933 = 1-546 inches.
