Give reason why trucks carrying heavy load have more number of wheels

Answer 1

QUESTION :-

Give reason why trucks carrying heavy load have more number of wheels .

Answer :-

We know that :

Pressure = force / area

So :

pressure ∝ force .

pressure ∝ 1 / area .

Pressure is inversely proportional to the area .

This means that :

If the pressure is high , then the area should be high to withstand the pressure.

Answer to your question :-

As the truck carries heavy load , then it must be facing huge pressure.

To withstand the huge amount of pressure, the surface area of the truck has to be increased .

Hence the number of wheels are increased to increase the surface area of the truck.

So trucks have more number of wheels
