EXAMPLES TO THE SECOND SERIES OF TABLES. 
Table of Constants No. 2, p. 50. 
By this and the Second Series of Tables may be found the Scantlings 
of various Species of Timber, sufficient to carry when loaded, any given 
portion of the breaking weight. By the same tables also may be found 
the Deflection and Breaking Weight of any scantling of timber 
of the several species therein specified. 
To find the breaking weight of any Species of Timber of any dimension 
in the Second Series of Tables. 
When the weight is uniformly loaded. 
The value of c in Col. I. p. 50, multiplied by the tabular weight for 
the scantling in the Second Series of Tables gives the breaking weight. 
Example 8.— Required the breaking weight, uniformly loaded, of 
Riga Fir 16 feet long 12 in. by 8 in. 
By Col. I. p. 50, for Riga Fir ; c = 6-423. 
By Table XIII. p. 76, the tabular weight for 16 feet long 12 X 8, is 
72 cwts. 
6-423 X 72 = 462-45 cwts. ; the breaking weight required. 
When the weight is suspended from the middle. 
The value of c in Col. III. p. 50, multiplied by the tabular weight for 
the scantling in the Second Series, gives the breaking weight. 
Example 9. — Required the breaking weight, suspended from the 
middle, of Riga Fir 12 feet long 10 X 6. 
By Col. IIL p. 50, for Riga Fir ; c = 3-211. 
By Table X. p. 70, the tabular weight for 12 feet long 10 X6 is 
50 cwts. 
3-211 X 50 = 160-55 cwts.j the breaking weight required.
