A tractor weighing 12 tons has a support area of both tracks of 2.4 m2. How much ground pressure does the tractor produce?

To calculate the value of the pressure exerted on the ground by the mass of a given tractor, we apply the formula: P = Ftyazh / S = m * g / S, where m is the mass of the tractor (m = 12 t = 12 * 10 ^ 3 kg); g – acceleration due to gravity (let us take g ≈ 9.8 m / s2); S is the support area of both tracks (S = 2.4 m2).
Calculation: P = m * g / S = 12 * 10 ^ 3 * 9.8 / 2.4 = 117.6 * 10 ^ 3 / 2.4 = 49 * 10 ^ 3 Pa = 49 kPa.
Answer: A pressure of 49 kPa is applied to the ground from the side of a given tractor.
