Calculations for Energy Stored in My Flywheel
The formula that I am using is: Energy of the Flywheel= 1/2*Moment of Inertia*angular velocity^2 To find the moment of inertia, I need to use the formula kmr^2 (inertial constant* mass of flywheel* radius squared), which is the moment of inertia for a rotating disk. The inertial constant of a flat solid disk is about .606 . The mass of the flywheel is about 2.5lbs, which converts to about 1.13kg . The radius of the disk is 2.5 inches, which converts to about .064m . Putting this back into the moment of inertia formula, we find that the moment of inertia for my flywheel is about .0028 . To find the angular velocity, I need to convert the RPM, or Revolutions Per Minute, into radians per second, the basic unit for angular velocity. The rough conversion from RPM to radians/sec is about 1 rad/s is equal to 9.55 RPM, which means that 6000 RPM, the max RPM I was able to get my flywheel up to in the vacuum chamber, is equal to about 628.3 rad/s. Plugging this back i...
