Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A cylindrical disc of mass 3 kg and radius 0.2 m is rotating about its center. If a force of 12 N is applied tangentially at the edge, calculate both the angular acceleration and the net torque.

💡 Hint: Remember to calculate both torque and moment of inertia.

Challenge 2 Hard

Design a rotating device that uses torque to function. Explain how you'd optimize it for maximum angular speed.

💡 Hint: Think about the balance of mass and distance from the axis.
