Most of the mass of a flywheel is concentrated at the rim so as to have large moment of inertia for the same mass.This is due to the fact that the moment of inertia varies as the square of the distance from the axis of rotation.
Most of the mass of a flywheel is concentrated at the rim so as to have a larger moment of inertia for the same mass. This is due to the fact that the moment of inertia varies as the square of the distance from the axis of rotation.
By concentrating the mass at the rim of the flywheel, the rotational inertia is maximized, storing more rotational energy for a given mass. This design allows the flywheel to store and release energy more efficiently, making it more effective in applications such as energy storage or stabilizing systems. Additionally, having the mass concentrated at the rim can increase the angular momentum, which can help maintain the flywheel's kinetic energy during operation.
In rotating systems like a flywheel, how the mass is distributed is just as important as total mass. To maximize moment of inertia (the equivalent of inertial mass) you want the mass as far to the outside as possible. A flywheel of uniform thickness has only 60% the moment of inertia compared to one that's all rim.
On the outer rim. Further away from the axis point.

The south rim offers the panoramic views you most likely have seen in pictures, but it is the most crowded. The north rim offers more trees and shade making it a lot different. For a first time visitor I would go to the south rim because it is the most spectacular and there are also places where you can beat most crowds especially if you hike a couple miles into the canyon.
Perhaps the Rim to Rim to Rim (RRR) run. It is more of a fitness test then a hike, but is a must-do among extreme athletes.
One can find images of a car rim at YouTube. One can also find it from the repair shop that sells car rim. Most car dealership also have car rim images on their websites.

The answer depends on what you mean by "better." The North Rim is higher, cooler, more isolated, more arboreal, and has far fewer visitors. It also has fewer tourist facilities, which is a plus or a minus depending on how you view their presence. Which rim has better views is subjective, but most people think the most iconic viewpoints are on the South Rim.
