* Example.— Pine 8 feet long, . . 16-01 in. by 3 in., or 15-21 by 3^ or 14-54 
by 4, or 13-99 by 4^ or 13-50 by 5, or 1271 by 6, or 12-07 by 7, or 11-54 by 8, 
with 146'28 cwts. uniformly loaded, or 91'42 cwts. suspended from the 
middle, deflects ^ of an inch. 
The breaking weight of Red Pine 8 ft. long, 14-54 in. by 4 in., is 5-784 x 146-28 = 846 
cwts. uniformly loaded, or 4'627 x 91-42=423 cwts. suspended from the middle.
