The weight of the tractor is 10 tons. The length of the support of each track is 200 cm, and the width is 50 cm. Find the weight of the tractor and the pressure on the ground.

Tractor ground pressure:
P = F / S, F – pressure force (F (tractor weight) = Fт = m * g, m – tractor weight (m = 10 t = 10 * 10 ^ 3 kg), g – gravitational acceleration (g = 10 m / s ^ 2)), S is the area of the tractor tracks (S = 2 * a * b, a is the length of the track (a = 200 cm = 2m), b is the width of the track (b = 50 cm = 0.5 m) ).
Let’s calculate the weight of the tractor and its pressure on the ground:
F = m * g = (10 * 10 ^ 3) * 10 = 100000 N = 100 kN.
P = F / S = F / (2 * a * b) = (10 * 10 ^ 3) * 10 / (2 * 2 * 0.5) = 50,000 Pa = 50 kPa.
Answer: The weight of the tractor is 100 kN, the pressure of the tractor on the ground is 50 kPa.
