c rate of doing work, viz., 33,000 foot-pounds per minute. Hence, to find the horse-power that a shaft will transmit, we must first find the work done, and then relate it to the speed. Take, for ex- ample, the case of a pulley, the symbols being the same as before — namely, P = driving force at rim… … Fig. 31. This is one of the most useful equations for calculations involving horse-power. By it the number of inch-pounds torsion for any horse-power can be at once ascertained. It should be clearly noted, however, that in this equation the bending moment does not enter at all. Hence any shaft…
