Challenge Problems

Push your limits with challenges.

Question 1

A crane has an operating radius (R) of 20 meters. The fulcrum distance (F) is 8 meters. Calculate X. What implications does this have for the crane's lifting capacity if the maximum tipping load is set for 200 tons?

💡 Hint: Use the formula to find X and analyze the tipping impacts from the X calculation.

Question 2

Assuming a crane has an overturning moment due to a load of 1000 kg at a distance of 2 meters from the tipping axis, calculate the stabilizing moment required to maintain stability if the central weight of the crane is 800 kg acting at 1.5 meters.

💡 Hint: Recognize the relationship between weight distribution and distance.
