# The tractor weighs 6000 kg and has an area of 2000 cm. What pressure does it exert on the soil?

October 2, 2021 | education

| Task data: m (tractor weight) = 6000 kg; S (support area of tractor tracks) = 2000 cm2.

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

SI system: S = 2000 cm2 = 2000 * 10-4 m2 = 0.2 m2.

1) Let’s calculate the force with which the mass of the tractor acts on the soil: F = m * g = 6000 * 10 = 60,000 N.

2) Determine the pressure of the tractor on the soil: P = F / S = 60,000 / 0.2 = 300,000 Pa or 300 kPa.

Answer: The tractor will exert a pressure of 300 kPa on the soil.
