The motor shown in Fig. P6-47 develops 100 hp at a speed of 360 rpm. Gears A and B deliver 40 hp and 60 hp, respectively, to operating units in a factory. If the maximum shearing stress in the shafts must be limited to 12 ksi, determine a. The minimum satisfactory diameter for the motor shaft. b. The minimum satisfactory diameter for the power shaft. (1 hp=745,7 watts); (1 ksi=6,89 MPa); (1 ft=0,30 m)

Power Transmission Elements

It is defined as the energy transfer from one location to another location. The energy will start moving from the energy generation source to the energy applied position to obtain the work output. From this method, a large amount of electric energy moves from the power station to various electrical substations.
