Challenge Problems
Push your limits with challenges.
Question 1
A crane is lifting a load at different luffing angles: 30°, 45°, and 60°. Calculate the operating radius at each angle if the base distance is 10 meters. Discuss the implications of each angle on stability.
💡 Hint: Use cosine for distance calculations and consider how it affects stability.
Question 2
During a lifting operation, a crane's boom is luffed improperly, leading to a potential tipping scenario. Identify the critical factors that should be adjusted to ensure stability and safety.
💡 Hint: Think safety first: balance and weigh options.
