A tractor weighing 112 kN exerts a pressure of 50 kPa on the ground. Determine the area of contact of the tractor tracks with the ground.
To find the value of the area of contact of the tracks of a given tractor with the ground, we will use the formula: P = Ft / S = Pt / S, from where we express: S = Pt / P.
Values of variables: Pt – weight of a given tractor (Pt = 112 kN = 112 * 10 ^ 3 N); P – ground pressure (P = 50 kPa = 50 * 10 ^ 3 Pa).
Calculation: S = PT / P = 112 * 10 ^ 3 / (50 * 10 ^ 3) = 2.24 m2.
Answer: The area of contact of the tracks of a given tractor with the ground is 2.24 m2.
