SpletSliding friction on ice and snow is characteristically low at temperatures common on Earth’s surface. This slipperiness underlies efficient sleds, winter sports, and the need for specialized tires. Friction can also play a micro-mechanical role affecting ice compressive and crushing strengths. Researchers have proposed several mechanisms thought to … The preceding paper has shown that the sliding friction bet ween metals decreases in a regular manner as the temperature is raised, provided that the chemical nature of the surface layers remains unchanged. The behaviour of the friction at temperatures near the melting-point was not investigated.
