Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A uniform rod rotates about an axis through its center and perpendicular to its length. Discuss the implications of its moment of inertia tensor during this rotation.

💡 Hint: Think about how mass is distributed and how it affects motion.

Challenge 2 Hard

A satellite is spinning and experiences torque from gravity. Predict the nature of its angular acceleration and subsequent motion even if the velocity remains constant.

💡 Hint: Consider how external forces affect rotation.
