Question

Which of the following types of circular bodies, Same mass and radius will have the largest moment of inertia ?
a)Solid disc
b)Cylindrical disc
c)Ring
d)Annular disc

Answer 1

Answer:

A. Ring

Explanation:

hope it helps you

Answer 2

Answer:

The correct answer is c)Ring

Explanation:

A ring has extra second of inertia than a circular disc of equal mass and radius, about an axis passing thru its centre of mass perpendicular to its plane, because. answer: a hoop has a larger moment of inertia due to the fact its entire mass is focused at the rim at a maximum distance from the axis.

a ring has greater second of inertia than a round disc of same mass and radius, about an axis passing through its centre of mass perpendicular to its aircraft, due to the fact

solution:

a ring has a larger moment of inertia because its entire mass is concentrated on the rim at a most distance from the axis.

second of inertia

second of inertia is defined as the amount expressed by means of the body resisting angular acceleration that's the sum of the made from the mass of each particle with its square of a distance from the axis of rotation.

it is able to be described as a amount that makes a decision the amount of torque needed for a selected angular acceleration in a rotational axis.

second of Inertia is also called the angular mass or rotational inertia.
