Explain the role of the differential lock in improving traction for heavy equipment operating on slippery surfaces.

The differential lock is a mechanical device used in heavy equipment to improve traction when operating on slippery or uneven surfaces. A differential is a component in the axle that allows each wheel to rotate at different speeds, which is necessary when turning. However, on slippery surfaces, the wheel with the least traction will spin freely, while the wheel with more traction receives little or no power. This can leave the equipment stuck. The differential lock, when engaged, effectively locks the two wheels on an axle together, forcing them to rotate at the same speed. This ensures....
