Questions and Answers

What is Euler's rotation theorem?

Euler's rotation theorem states that simultaneous rotation along a number of stationary axes at the same time is impossible; if two rotations are forced at the same time, a new axis of rotation will result.

What does rotation around a fixed axis exclude?

Rotation around a fixed axis excludes the possibility of the instantaneous axis of rotation changing its orientation and cannot describe phenomena such as wobbling or precession.

What is the assumption about stable rotation around a fixed axis?

The assumption is that the rotation is stable, such that no torque is required to keep it going.

How do the kinematics and dynamics of rotation around a fixed axis compare to free rotation of a rigid body?

<p>The kinematics and dynamics of rotation around a fixed axis of a rigid body are mathematically much simpler than those for free rotation of a rigid body.</p> Signup and view all the answers

What is the mathematical analogy for rotation around a fixed axis of a rigid body?

<p>The kinematics and dynamics of rotation around a fixed axis of a rigid body are entirely analogous to those of linear motion along a single fixed direction, which is not true for free rotation of a rigid body.</p> Signup and view all the answers
