Challenge Problems
Push your limits with challenges.
Question 1
A worker needs to lift a load of 500 N. If they use a lever with a load arm of 4 m, at what distance should they apply the effort to balance the load?
💡 Hint: Rearrange the formula to solve for the distance.
Question 2
Design a lever system that allows a person to lift a 300 N load with just 100 N of effort. Calculate the necessary lengths of the load arm and effort arm.
💡 Hint: The ratio of forces will help to identify proportions of the arms needed.
