Challenge Problems
Push your limits with advanced challenges
A crane is set to lift two loads: one load of 8 tons is lifted at a radius of 4 meters, while a boom weighing 1.5 tons is also attached. Calculate the total overturning moment acting on the crane. What would you suggest to ensure stability?
💡 Hint: Consider how to balance loads.
During an operation, a crane experiences a gust of wind that applies an additional load of 2 tons while lifting a load of 10 tons at a distance of 5 meters from the fulcrum. What effect does this have on both the overturning and stabilizing moments? Calculate.
💡 Hint: Can you quantify the changes caused by wind load?
