Power Generation from Constant Rotating Mass

Click For Summary
SUMMARY

The discussion centers on calculating the electrical power generated by a rotating mass system, specifically with parameters of mass M=60 kg, radius R=5 meters, and velocity V=10 meters per second. It concludes that the device cannot generate electrical power without a specific mechanism to convert rotary motion into electrical energy. Key equations mentioned include P = dW/dt and P(t) = torque(t) * angular_velocity(t), which are essential for determining the system's power output.

An object with a mass M is rotating around an axis, with an arm of radius R at a certain speed V.
Assuming that the movement is constant, and a 100% efficiency, how many watt of electrical power can this device generate ?

For example purpose, we can take M=60 kg, R=5 meters and V=10 meters per second.

I can't find all the formulas and am lost with the units.

Thanks a lot

That device can't generate any electrical power.
 
Hello!

I assume it is some kind of engine, and rotary motion somehow generates electricity through another undisclosed system.

I would try to calculate how much Power our system has at any point, and if this motion is constant and translates to Electrical Energy - this is the generated power.

Try to find the work done by the system and how much time it takes to preform (lets say for one revolution) and then you can find the power of the system: P = dW/dt

(useful equation: P(t) = torque(t) * angular_velocity(t) )
