Flywheel that will simulate a load of .104 slug-feet squared

[Ray Fernandez]

Any one can help with the following, i need to know the weight and radius of flywheel that will simulated a load of .104 slug-feet squared, calculation base in friction

 

[mfb]

There is no fixed weight and radius, a larger radius and smaller weight will give similar results as a smaller radius and larger weight.
There is a formula for the moment of inertia of flywheels (it depends on the geometry).

Those US-units are weird...
