Which of the following physical quantities determines the rotational inertia of a rigid body about a specified axis of rotation?

  1. A
    Total mass of the body and the spatial distribution of mass about that axis
  2. B
    Total mass and instantaneous angular velocity of the body
  3. C
    External torque applied and direction of angular acceleration
  4. D
    Only the magnitude of the applied torque
View Answer & Solution

Correct answer · Option A

Total mass of the body and the spatial distribution of mass about that axis

Explanation

Moment of inertia depends on the total mass, the shape and size of the body, and the distribution of mass relative to the axis of rotation.

Given below are two statements: Statement I: The kinetic energy of a body of moment of inertia \( I \) rotating with an angular velocity \( \omega \) about a fixed axis is given by \( K = \frac{1}{2} I \omega^2 \). Statement II: The moment of inertia of a rotating rigid body changes if its angular velocity is doubled. In the light of the above statements, choose the most appropriate answer from the options given below:→Given two vectors \( \mathbf{a} = 3\hat{i} - 4\hat{j} + 5\hat{k} \) and \( \mathbf{b} = -2\hat{i} + \hat{j} - 3\hat{k} \), the cross product \( \mathbf{a} \times \mathbf{b} \) is equal to:→Consider the following statements regarding rotational motion about a fixed axis: (A) Only those components of external torques that lie along the axis of rotation can cause the body to rotate about the axis. (B) Torques perpendicular to the fixed axis are balanced by the constraint forces exerted by the hinges/supports. (C) Forces parallel to the axis of rotation produce non-zero torque about that axis.
