According to Euler's rotation theorem, what happens when two rotations are forced at the same time?
According to Euler's rotation theorem, what happens when two rotations are forced at the same time?
- The rotations combine to form a new axis of rotation (correct)
- The rotations cause the object to precess
- The rotations cancel each other out
- The rotations cause the object to wobble
What assumption is made about the rotation around a fixed axis?
What assumption is made about the rotation around a fixed axis?
- The rotation is in three-dimensional space
- The rotation is stable and requires no torque to keep it going (correct)
- The rotation is unstable
- The rotation requires torque to keep it going
