HORSE-POWER TRANSMITTED BY COLD ROLLED SHAFTING. FIRST MOVERS OR HEAD SHAFTS WELL SUPPORTED BY BEARINGS.
The above table is figured by the following rule: Multiply the cube of the diameter of the shaft by the revolutions per minute and divide by 100.
The table on the opposite page applies to head shafts supported by bearings close to each side of the main pulley so as to wholly guard against the transverse strain.
To find the diameter of shaft necessary to carry safely the main pulley at the center of a bay, use the table given below in connection with the one on the opposite page.
