The surface area of the tractor tracks is 1.4 m2. Determine the weight of the tractor if it exerts a pressure of 37 kPa on the ground.
To determine the value of the mass of the specified tractor, you must use the formula: m = P * S / g.
Variables: P is the pressure of the mass of the specified tractor on the ground (P = 37 kPa = 37 * 10 ^ 3 Pa); S – the area of contact of the tracks of the specified tractor with the ground (S = 1.4 m2); g – acceleration due to gravity (g ≈ 10 m / s2).
Calculation: m = P * S / g = 37 * 10 ^ 3 * 1.4 / 10 = 5.18 * 10 ^ 3 kg;
Answer: The weight of the indicated tractor is 5.18 tons.
