They help us to transport things. Most vehicles have wheels. Cars, trucks, trains, motorcycles, buses, etc. Then there are things called conveyor belts. They too have an axle and a component similar to a wheel called a roller and has a wide belt running over it to transport goods in countless factories. Many machinery have components similar to a wheel/axle design that helps to make them function. Those are called pulleys. Various pulleys types exist for ropes, V-belts, cable, etc. One can not even imagine a life without the simple wheel and axle.
