Challenge Problems
Push your limits with advanced challenges
A force of 15 N is applied at a distance of 0.8 m from a pivot. If the moment arm increases to 1.2 m, what is the new torque produced?
💡 Hint: Use the same formula for torque.
Design a scenario where a person needs to apply at least 20 N of force at a moment arm of 0.5 m. What changes if the moment arm is increased to 2 m?
💡 Hint: Remember the relationship between torque and moment arm.
