A rim enhancing mass refers to a type of imaging finding often seen in medical imaging, particularly in CT or MRI scans. It typically indicates a lesion or abnormal growth that enhances at the edges or periphery, suggesting the presence of a tumor or other pathological process. The enhancement usually occurs due to the accumulation of contrast agent in the vascularized tissue surrounding the mass, often indicating its aggressive nature or the presence of inflammation. Such findings require further evaluation to determine the underlying cause and appropriate management.
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.

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.
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.

A non-enhancing mass typically refers to a lesion or abnormal tissue growth that does not show increased contrast uptake on imaging studies like MRI or CT scans. This can indicate a benign or stable condition, but further evaluation and monitoring may be needed to confirm the nature of the mass.

A heterogeneous enhancing mass refers to an abnormal growth or lesion in the body that appears different in composition or density on imaging scans such as MRI or CT. The term "heterogeneous" indicates that the mass contains areas of varying densities or components, which can be indicative of different types of tissue or pathology within the mass. The "enhancing" aspect suggests that the mass is taking up contrast material more than surrounding tissues, often indicating increased vascularity or metabolic activity within the mass. Further evaluation and testing are typically needed to determine the nature and potential significance of a heterogeneous enhancing mass.

RIM owns RIM
Using a free coaster back rim in BMX riding allows for smoother and more controlled backward riding without the need to pedal. This can help riders perform tricks more easily and with greater precision, enhancing their overall riding experience.
