What is a disadvantage of using ladders to distribute weight across ice?

• A. Ladders could sink if the ice breaks underneath.
• B. Ladders are too loud for noisy environments.
• C. Ladders cause ice to melt more quickly.
• D. Ladders require a large crew to deploy.

Answer: (A)

Distributing weight on ice is about lowering the pressure on any given spot so the ice doesn’t fail. A ladder concentrates most of its weight at its feet, which are small contact points. If the ice is thin or cracked, those concentrated loads can cause the ice to crack or give way under the ladder. When the ice fails, the ladder and the person on it can sink or fall through, creating a serious hazard. This is the key danger of using ladders on ice: they don’t spread weight over a wide surface, so localized failure is more likely. The other points—ladders being loud, causing ice to melt, or needing a large crew—don’t address the fundamental issue of how the load interacts with the ice’s strength.
