Question

Why do the load carrying heavy vechicle have large number of whaals​

Answer 1

Answer:

hope it will help u dear

Explanation:

So, the load carrying heavy vehicles have large number of wheels so that the pressure on the road is reduced due to larger contact area. Also, using large number of wheels ensures that the force due to the load is shared among the tyres and no single tyre is under stress.

Answer 2

As the load carrying large and heavy vehicle more and wide area. Hence, it will apply more pressure in ratio to its area and weight. To distribute this pressure, there will be obvious need of force. This force is given by the tires. Hence, more the pressure, it will need more force. And thus, more tires (large number of tires) would be used.

Hope this answers your question.
