For Scantlings 15^ inches deep, multiply the weights in this table 
by |4s= 1"0677, and the deflections by |°=:-968.f 
* ETample 1. — Red Pine 15 in. by 11 in., 15 feet long, with 165 cwts. uniformly loaded, 
(one-eighth the breaking weight) deflects -247 of an inch; and with 165 cwts. suspended from 
the middle, (one-fourth the brealdug weight) the deflection is -394 of an inch. 
f* Example 2. — Red Pine 15 J in. by 11 in., 15 feet long, with 165 x 1-0677 = 176-18 
cwts. uniiformly loaded, (one-eighth the breaking weight) deflects -247 x -968 = -239 of an 
inch; amd with 176-18 cwts. suspended from the middle, (one-fourth the breaking weight) 
the defleiction is -394 x 968 = -381 of an inch.
