Challenge Problems
Push your limits with challenges.
Question 1
A crane is rated to lift a maximum load of 5000 kg. If a new boom weighing 1500 kg is added, what is the maximum load the crane can lift now, considering the boom's weight affects the lifting capacity?
💡 Hint: Think about how the crane's weight impacts its lifting capability.
Question 2
