Hey can someone help, im having trouble converting alot.

IP The weight of your 1440 kg car is supported equally by its four tires, each inflated to a gauge pressure of 30.0 lb/in^2.

What is the area of contact each tire makes with the road?

What gauge pressure is required to give an area of contact of 122 for each tire?

4*gauge pressure*area=weight of car

4*30lb/in^2=1440kg*1lb/.454kg

check my thinking

so if the answer wants cm^2 what would be the conversion?

To find the area of contact each tire makes with the road, you can use the formula:

Area = Force / Pressure

In this case, the force exerted on each tire is equal to the weight of the car, which is 1440 kg. To convert this to force, we need to multiply it by the acceleration due to gravity, which is approximately 9.8 m/s^2. Therefore, the force is:

Force = 1440 kg * 9.8 m/s^2

Next, we need to convert the given pressure from lb/in^2 to a standard unit of pressure such as pascal (Pa). Since 1 lb/in^2 is approximately equal to 6895 Pa, we can calculate the pressure in pascals as:

Pressure = 30.0 lb/in^2 * 6895 Pa/lb/in^2

Finally, we can substitute these values into the formula to find the area of contact:

Area = Force / Pressure

Now, solving for Area will give us the answer to the first question.
