Challenge Problems
Push your limits with challenges.
Question 1
A crane is required to lift a load of 10,000 kg. The boom weighs 3,000 kg, and it experiences a wind load of 1,000 kg. Calculate the necessary stabilizing moment to ensure crane safety.
💡 Hint: Consider all inputs that could affect tipping.
Question 2
Analyze a scenario where the boom angle is increased from 30 degrees to 60 degrees. Discuss the implications this change has on the crane's stability and its lifting capacity.
💡 Hint: Think about how angles affect both distance and strength.
