4e.* For Scantlings If inches deep, multiply the weights in this table 
by 11= 1-3611, and the deflections by |.= -857.1 
* Example 1. — Red Pine \ \ in. by 1| in., 7 feet long, with "56 cwts. uniformly loaded, 
)Tie-eighlh the breaking weight) deflects -537 of an inch ; and with -56 cwts. suspended from 
le middle, (one-fourth the breaking weight) the deflection is '859 of an inch. 
[ f* Example 2 — Red Pine If in. by If in., 7 feet long, with -56 x 1-36 = 76 cwts. uni- 
armly loaded, (one-eiglith the breaking weight) deflects "537 y- ^='460 of an inch ; and with 
i?6 cwts. suspended from the middle, (one-fourth the breaking weight) the deflection is 
859 X 6 = 736 of an inch. 
*^* To find the Scantlings of Red Pine and other kinds of timber, sufficient to carry, when 
loaded, one-re"" part, or any givon portion of the breaking weight, see the Table and 
i Examples referred to in the preceding page.
