Concept explainers

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.

How do you calculate the velocity ratio of revolutions per minute for the gear C
a) Figure Q3a shows a stage 1 to stage 2 compound gear train through from Gears A, B, C to D. If the input shaft rotates at 1300 revolutions per minute (rpm), calculate the angular velocity (w) in rad/s at the output shaft of the compound gear train. See below for the number of teeth for Gears A, B, C & D.
