Question

For a car of weight 9000 N the recommended tyre pressure is 18 N/cm².Find

the area of each tyre in contact with the ground​

Answer 1

mathematically,

`pressure = (force)/(area)`

but weight= Force.

given pressure

18N/cm^2

and Force = 9000N

making area the subject in the relation above.

`Area = (force)/(pressure)`

substitute their values into the equation

`Area = (9000)/(18)`

`Area = 500 {cm}^(2)`
