the moment of inertia of a solid cylinder about an axis passing through its COM and parallel to its length is mr2/2 where r is the radius.

(1/2) mr2, assuming the axis of rotation goes through the center, and along the axis of symmetry.

A rotating body that spins about an external or internal axis (either fixed or unfixed) increase the moment of inertia.

The moment of inertia of a hollow cylinder is given by the formula I = 1/2 * m * (r_outer^2 + r_inner^2), where m is the mass of the cylinder, r_outer is the outer radius, and r_inner is the inner radius of the cylinder. This formula represents the distribution of mass around the axis of rotation.

The moment of inertia of an object depends on its mass distribution and shape. For simple shapes, such as a point mass or a solid cylinder, mathematical formulas can be used to calculate the moment of inertia. For complex shapes, numerical methods or integration techniques may be necessary to determine the moment of inertia.

Moment of inertia opposes turning anything! Besides which, the answer would depend on the mass of the cylinder as well as the which axis which it is meant to rotate around.

The types of moment of force are torque (or moment of force), bending moment, and twisting moment. Torque is the measure of the force causing an object to rotate around an axis, bending moment is the measure of the force causing an object to bend, and twisting moment is the measure of the force causing an object to twist.

if they are short or in tension they are the same, when they bend the hollow tube has a bigger second moment of area and so is stronger to any bending moment

The moment of inertia of a hollow disk is given by (1/2) * m * (r_outer^2 + r_inner^2), where m is the mass of the disk, r_outer is the outer radius, and r_inner is the inner radius. This formula accounts for the distribution of mass around the central axis of the disk.

Sources of error in the experiment of moment of inertia of a solid cylinder can include friction in the rotating system, inaccuracies in the measuring instruments such as rulers or calipers, variations in the dimensions of the cylinder, and errors in the calculation of the rotational inertia formula. Additionally, external factors like air resistance or vibrations can also introduce errors in the experiment.
