* Example.—Rc^ Pine 15 feet long, 15-34 in. by 4 in., or 14-75 by 4i, or 
14-24 by 5, or 13-40 by 6, or 12-73 by 7, with 86.78 cwts. uniformly 
loaded, or 54 24 cwts. suspended from the middle, deflects ii of an inch. 
The breaking weight of Red Pine 15 ft. long, 13-40 in. by 6in., is 6-621 x 86-78 = 574-6 
cwts. uniformly loaded, or 5-297 x 54-24 = 287-3 cwts. suspended from the middle.
