Question

4. Тиск гусеничного трактора на грунт становить 27 кПа? Що це означає? З якою силою трактор тисне на ґрунт, якщо площа, на яку спираються його гусениці, становить 2,9 м квадратних​

Answer 1

Ответ:Дано:

P=27кПа=27000Па

S=2.9мквадратних

F-?

Объяснение:

P=F\S

F=P*S

F=27000*2.9=78300H

Відповідь:трактор тисне на грунт із силою 78 300 H

Answer 2

Understanding Ground Pressure of a Tracked Vehicle

The ground pressure of a tracked vehicle, such as a tractor, refers to the force exerted by the vehicle on the ground per unit area. In this case, the ground pressure of the tractor is 27 kPa, and the area on which its tracks rest is 2.9 square meters.

Calculation of Force Exerted: To calculate the force exerted by the tractor on the ground, we can use the formula: \[ \text{Force} = \text{Pressure} \times \text{Area} \]

Substituting the given values: \[ \text{Force} = 27 \, \text{kPa} \times 2.9 \, \text{m}^2 \]

Let's calculate the force using the given values.

Calculation of Force Exerted by the Tractor

The force exerted by the tractor on the ground can be calculated using the given ground pressure and the area on which its tracks rest.

\[ \text{Force} = 27 \, \text{kPa} \times 2.9 \, \text{m}^2 \]

The force exerted by the tractor on the ground is approximately 78.3 kN (kilonewtons).

Interpretation: This means that the tractor exerts a force of approximately 78.3 kilonewtons on the ground through its tracks. This force is distributed over the 2.9 square meters of area on which the tracks rest.

In practical terms, a higher ground pressure can lead to greater soil compaction and potentially cause damage to the ground, especially in soft or sensitive terrains. It's important to consider ground pressure when operating heavy machinery on different types of surfaces to minimize environmental impact and soil damage.
