THIRD SERIES — TABLES OF SCANTLINGS 
TABLE VI. Continued. 
Scantlings of Red Pine when acted upon by two forces P and Q, viz., 
P in the direction of the depth, Q in the direction of the breadth. 
In this table, Q,=P; P = pressure upon each foot in length; IBreaDTH

* Example.— ^ei Pine 10 feet long, 10-89 in. by 10-89 in., with 10x 12-25 = 122-5 
cwts. pressure in the direction of the depth, and with 122-5 cwts. pressure in the direction 
of the breadth, deflects each way .i-g. or ^ of an inch. 
The breaking weight, in the direction of the depth, and also of the breadth, of Ked Pine 
10 feet long, 10-89 in. by 10-89 in., is 10 x 12-25 x 8-447 = 1034-75 cwts., the pressure 
being uniform in both cases ; or one lialf of that weight, viz. 517"37 cwts., if the pressures 
act in the middle.
