Question

Rubber tyres are preferred to steel tyres. Why?

Answer 1

Steel is far more durable than rubber. We need a material that can be moulded into any shape and can be inflated and deflated to make tyres. Steel is substantially more elastic than rubber, hence it lacks the desired qualities for tyre manufacturing.

Complete answer:
Rubber tyres are preferable over steel tyres because driving over pebbles would be an extremely harsh ride with steel tyres. Rubber tyres are flexible and will glide over small pebbles and rocks with ease.
Rubber tyres are typically flexible and will glide over even the tiniest pebbles. Furthermore, rubber tyres will eventually wear out, necessitating the purchase of new ones.
The ability of a substance to restore its previous shape after being subjected to an external force is known as elasticity. The Young's modulus of a material is defined as the ratio of stress applied to the strain produced in it.
When we apply the same amount of stress to steel and rubber with the same cross-sectional area, we can see that rubber is stretched more than steel. When compared to steel, the strain produced by rubber is substantially greater. This means that steel has a higher Young's modulus of elasticity than rubber, and hence has more elasticity.
The elasticity of a material is proportional to its resistance to change. When tension is applied to rubber, strain is formed in it, causing it to stretch. The greater the strain, the less elastic the material is.

Note:
Rubbers are in charge of carrying your car's weight and can have a significant impact on the quality of your ride. Rubber is a great material since it is durable, resistant to temperature fluctuations, and inexpensive.
