* Example.— Ktd, Piue 13 feet long, 13-32 in. by li iu., or 12-65 by If, or 12-10 by 
2, . . or 10-57 by 3, . . or 9-23 by 4|, or 8-91 by 5, with 31-87 cwts. uniformly 
loaded, or 19-92 cwts. suspended from the middle, deflects JL3 of an inch. 
The breaking weight of Red Pine 13 feet long, 10-04 in. by 3i in., is 6-809 x 31-87 = 
217-0 cwts. uniformly loaded, or 5-447 x 19-92 = 108-5 cwts, suspended from the middle.
