Question

Масса трактора 5710 кг. Трактор опирается на площадь 1,4 м2. Какое давление производит трактор на опору? 9 = 9,8 н/кг. Ответ: р=. Па.

Answer 1

Ответ:

36190Па

Объяснение:

Дано:

m=5170кг

S=1,4m²

g=9,8H/кг

Решение:

p=F/S

F=mg

F=5170кг×9,8Н/кг=50666Н

p=50666Н÷1,4м²=36190Па

Answer 2

Calculation of Pressure

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

Pressure = Force / Area

Given: - Mass of the tractor = 5710 kg - Area of the support = 1.4 m² - Acceleration due to gravity = 9.8 m/s²

First, we need to calculate the force exerted by the tractor on the support. The force can be calculated using Newton's second law of motion:

Force = Mass x Acceleration

Substituting the given values:

Force = 5710 kg x 9.8 m/s²

Now, we can calculate the pressure:

Pressure = Force / Area

Substituting the calculated force and given area:

Pressure = (5710 kg x 9.8 m/s²) / 1.4 m²

Calculating the above expression gives us the pressure exerted by the tractor on the support.

Let's calculate it:

Pressure = (5710 kg x 9.8 m/s²) / 1.4 m²

Using a calculator, we find:

Pressure ≈ 40,964.29 Pa

Therefore, the pressure exerted by the tractor on the support is approximately 40,964.29 Pascal (Pa).
