Question

Масса трактора 15т. какое давление производит трактор на почву , если площадь опоры его гусениц 1,5мв квадрате ? ответ выразить в кПа

Answer 1

15т = 15000 kg

Fт = mg 
p = Fт/S = mg/S = (15000 * 10)/1,5 = 100000 Па = 100 кПа

Answer 2

Calculating Pressure Exerted by the Tractor

To calculate the pressure exerted by the tractor on the ground, we can use the formula:

Pressure (P) = Force (F) / Area (A)

Given: - Mass of the tractor (m) = 15 tons = 15000 kg - Acceleration due to gravity (g) = 9.81 m/s^2 - Area of contact (A) = 1.5 m^2

First, let's calculate the force exerted by the tractor on the ground using the formula:

Force (F) = Mass (m) x Acceleration due to gravity (g)

Force (F) = 15000 kg x 9.81 m/s^2

Force (F) = 147150 N

Now, we can calculate the pressure exerted by the tractor on the ground using the formula:

Pressure (P) = Force (F) / Area (A)

Pressure (P) = 147150 N / 1.5 m^2

Pressure (P) ≈ 98100 Pa

So, the pressure exerted by the tractor on the ground is approximately 98100 Pa.
