Challenge Problems
Push your limits with advanced challenges
An object with a moment of inertia of 8 kg·m² is rotating at 5 rad/s. If a torque of 3 N·m is applied in the opposite direction, what will be the new angular velocity after 2 seconds?
💡 Hint: Use the analogy from linear motion, just remember the direction of torque.
A 2 kg rod is rotated about its center with one end supported. If 500 grams is added to one end of the rod increasing torque, what is the new moment of inertia of the system?
💡 Hint: Consider both the added mass and the pitching point for calculating the new balance.
