Question: Explain why shopping trolleys have small wheels?

Have you ever wondered why shopping trolleys have small wheels? You might think that bigger wheels would make them easier to push and steer, but there are actually some good reasons why small wheels are better for shopping trolleys. Here are some of them:

- Small wheels are cheaper and lighter than big wheels. This means that the trolley costs less to produce and transport, and it also reduces the weight that the shopper has to push.

- Small wheels have less rolling resistance than big wheels. This means that they require less force to move and they can roll faster on smooth surfaces, such as the supermarket floor.

- Small wheels have a smaller turning radius than big wheels. This means that they can make sharper turns and manoeuvre better in tight spaces, such as between aisles and around corners.

- Small wheels are less likely to get stuck or damaged by obstacles, such as curbs, steps, or uneven pavement. This reduces the risk of accidents and injuries for the shopper and the trolley.

So, next time you go shopping, you can appreciate the benefits of small wheels on your trolley. They may not look very impressive, but they are actually designed to make your shopping experience more convenient and efficient.
