Challenge Problems
Push your limits with challenges.
Question 1
A solid cube experiences a uniform gravitational field. If we define the cube's mass as 4 kg and its side length as 2 m, calculate the torque about an axis through one corner due to the weight of the cube.
💡 Hint: Use the torque equation while considering the right geometry of the cube.
Question 2
A cylinder is rotating with an angular velocity of 5 rad/s. It is subjected to a constant torque of 10 Nm. Calculate the change in angular momentum after 4 seconds.
💡 Hint: Remember that angular momentum is affected by the net torque applied over time.
