When would it be more practical to use wheel and axle then a lever?

Using a wheel and axle is more practical when the task involves moving heavy loads over distances, as it reduces friction and makes transportation easier. For example, in vehicles, the wheel and axle allow for smooth movement and greater efficiency compared to a lever, which is better suited for lifting or applying force over a shorter distance. Additionally, wheel and axle systems can cover ground more quickly, making them ideal for tasks that require mobility.
