The car puts pressure on the road 200 kPa. What is the area of contact of the wheels with the road

The car puts pressure on the road 200 kPa. What is the area of contact of the wheels with the road if the mass of the car is 3 tons?

Step one.

Let us determine what the force with which the car presses on the road will be equal, when from the condition of this problem we know that its mass is 3 tons:

3 tons is the same as 3000 kg;

F = m * g;

3000 * 10 = 30,000.

Step two.

Let us determine what the area with which this car is in contact with the road will be equal, when it is known from the condition of our problem that the pressure that it exerts on the road is equal to 200 kPa:

P = F / s;

200 kPa – this will be 200,000 Pa;

30000: 200000 = 0.15

Answer: 0.15 m2.
