What pressure does a 40t tank exert on the soil if the track area is 2m2?

Data: m (tank weight) = 40 t; S1 (area of one tank track) = 2 m2.

Reference data: g (acceleration due to gravity) = 9.81 m / s2 ≈ 10 m / s2.

SI: m = 40 t = 40 * 10 ^ 3 kg.

1) The force of pressure of the tank mass on the soil: F = m * g = 40 * 10 ^ 3 * 10 = 400 * 10 ^ 3 N.

2) The total area of two tank tracks: S = 2S1 = 2 * 2 = 4 m2.

3) The pressure that the tank will exert on the soil: P = F / S = 400 * 10 ^ 3/4 = 100 * 10 ^ 3 Pa = 100 kPa.

Answer: The tank exerts a pressure of 100 kPa on the soil (there is no correct answer).
