Question
Analyzing the stability of solutions to this set of equations yields the tennis racket theorem. For 10 points each:
[10h] Name this set of equations which states that L dot plus omega cross L equals the applied torque. These equations are the equations of motion for a rigid body.
ANSWER: Euler’s rotation equations [or Euler’s equations]
[10e] Euler names one kind of this class of forces proportional to the angular acceleration of a reference frame. This class of forces includes the Coriolis and centrifugal forces.
ANSWER: fictitious forces [accept pseudoforces; accept inertial forces; accept d’Alembert forces]
[10m] Euler angles can be used to describe this motion, during which the axis of rotation of a spinning body oscillates along the second Euler angle as the body precesses.
ANSWER: nutation
