Answer 2

Finding the Moment of Inertia of a Disk

To find the moment of inertia of a disk with mass T and radius R about an axis X lying in the plane of the disk, we can use the formula for the moment of inertia of a solid disk:

I = (1/2) * m * R^2

Where: - I is the moment of inertia - m is the mass of the disk - R is the radius of the disk

In this case, the mass of the disk is given as T and the radius is given as R. Therefore, the moment of inertia of the disk about the X-axis is:

I = (1/2) * T * R^2 Please note that the information provided in the search results was not directly applicable to the question. However, the formula for the moment of inertia of a solid disk is a well-known result in physics and can be used to calculate the moment of inertia in this case.
