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.

In the image on the right, there is a red gear G1 on the left with a radius of r1 = 2.81cm. Gear G1 is locked to the green gear G2 with a radius of r2 = 0.734cm. Gear G2 then shares the same axle as the blue circular saw G3, which has a radius of r3 known to make a full rotation every T = 0.836s. Using at least 6 significant digits in your calculations, compute the following: V3! 12.8cm. Gear G1 is W1 a) The angular speed wi of gear G1. Remember that angular speed is measured in radians per T3 r2 unit time. G2 b) The rim speed vi of gear G1. Since gears G1 and G2 are locked together, the rim speed of G2 is also v1. G1 G3 c) The angular speed w2 of gear G2. Since gear G2 and saw G3 share the same axle, the angular speed of G3 is also w2. d) The rim speed v3 of saw G3.
