Answer:
Use the formula to determine the contact area of each tire with the road.
Area divided by force yields pressure, as the equation suggests.
The weight of the car, which is 1500 kg, exerts a force on an area where pressure is at 2.2 x 10^5 Pa.
Supported by all four tires, we must first determine the total force.
Weight of car is 1500 kg multiplied by 9.8m/s^2 equals =14700 N, also known as total force.
Equally sharing the load, four tires are responsible for supporting the vehicle.
Each tire carries a force that equals the total force divided by 4, which is equivalent to 3675 N as calculated from a total force of 14700 N.
Each tire's contact area with the road can now be calculated.
3675 N divided by 2.2 x 10^5 Pa equals the area. This area can also be described as force divided by pressure.
Approximately 16.7 cm^2 or 1.67 x 10^-2 m^2 is the designated area.
The contact area between the road and each tire measures exactly 16.7 cm^2.
