Question

Spherical rotors have only one moment of inertia.
a. True
b. False

Answer 1

False. Spherical rotors do not have only one moment of inertia. The moment of inertia depends on the shape and mass distribution of the object.

Step-by-step explanation:

False

Spherical rotors do not have only one moment of inertia. The moment of inertia depends on the shape and mass distribution of the object. A spherical rotor can have different moments of inertia depending on the axis of rotation.

For example, consider a solid sphere rotating about an axis passing through its center. Its moment of inertia is given by I = (2/5) * M * R^2, where M is the mass of the sphere and R is its radius. On the other hand, a solid cylinder rotating about an axis passing through its center would have a different moment of inertia.
