What happens when the distance from the crane's center of gravity to the tipping axis is increased?

• A. It decreases stability
• B. It has no effect on stability
• C. It increases stability
• D. It causes structural damage

Answer: (C)

When the distance from the crane's center of gravity to the tipping axis is increased, it increases stability. This is due to the principles of leverage and balance. The farther the center of gravity is from the tipping axis, the greater the moment arm. This larger moment arm provides a more substantial counteracting force against tipping, thereby enhancing the crane's overall stability. In practical terms, when a crane is lifted at an angle or is extended further away from its base while carrying a load, the center of gravity shifts. If this distance becomes greater, the crane's ability to resist tipping improves. The distribution of weight and the balance of forces play critical roles in maintaining stability, ensuring that the crane does not topple over during operations. In contrast, diminishing the distance could lead to a higher risk of instability, making the correct understanding of these distances essential for safe crane operation.
