Answer:
28.5 lbs/in²
Explanation:
The following data were obtained from the question:
Area (A) = 4578 cm²
Force applied (F) = 9172 kg
Pressure (P) =..?
Next, we shall convert 4578 cm² to in².
This can be obtained as follow:
1 cm² = 0.155 in²
Therefore,
4578 cm² = 4578 cm² / 1 cm² × 0.155 in²
4578 cm² = 709.59 in²
Therefore, 4578 cm² is equivalent to 709.59 in²
Next, we shall convert 9172 kg to pounds (lbs) This is illustrated below:
1 kg = 2.20462 lbs
Therefore,
9172 kg = 9172 kg / 1 kg × 2.20462 lbs
9172 kg = 20220.8 lbs
Therefore, 9172 kg is equivalent to 20220.8 lbs
Finally, we shall determine the pressure as follow:
Area (A) = 709.59 in²
Force applied (F) = 20220.8 lbs
Pressure (P) =..?
P = F/A
P = 20220.8 lbs / 709.59 in²
P = 28.5 lbs/in²
Therefore, the tire pressure exerted of the surface is 28.5 lbs/in²
