Challenge Problems
Push your limits with challenges.
Question 1
A rigid body is rotating freely in 3D. If the inertia tensor is represented as a diagonal matrix, describe how its rotation can be analyzed using Euler's equations.
π‘ Hint: Identify the key components of the inertia tensor in the equations.
Question 2
Assume a satellite's axis is exhibiting precessional motion. Calculate the torque required to maintain stable rotation if the angular velocity changes at 2 rad/s.
π‘ Hint: Link torque to inertia calculations based on angular velocity changes.
