Question

помогите плиз (_: з по болотистому ґрунту пройшов всюдихід, тиск якого на ґрунт дорівнював 30000 Па. Визначте, чи пройде по цій дорозі трактор масою 7 т, якщо площа однієї гусенеці дорівнює 0,7м²​

Answer 1

Ответ: не пройдет.

Объяснение:

Дано:

Рдоп=30000Па

m=7т=7000кг

S=0,7м³

--------------

Р-?

P=F/S=mg/S=7000*10/0,7=100000Па>30000Па

Трактор не пройдет, так как его  давление на грунт значительно больше допустимого

Answer 2

To determine whether a tractor weighing 7 tons can pass through a road with a boggy soil, we need to consider the pressure exerted by the tractor on the ground and compare it to the bearing capacity of the soil. The pressure exerted by the tractor can be calculated using the formula:

Pressure = Force / Area

Given that the tractor weighs 7 tons, we need to convert this weight to force. Since 1 ton is equal to 1000 kg, the weight of the tractor in kilograms is:

Weight = 7 tons * 1000 kg/ton = 7000 kg

The area of one track of the tractor is given as 0.7 m².

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

Pressure = 7000 kg / 0.7 m²

Calculating this, we find:

Pressure = 10000 Pa

The pressure exerted by the tractor on the ground is 10000 Pa, which is less than the given pressure of 30000 Pa. Therefore, the tractor should be able to pass through the road with boggy soil without any issues.

Please note that the above calculation assumes that the weight of the tractor is evenly distributed over the area of the tracks. Additionally, the calculation does not take into account other factors such as the depth of the boggy soil or the traction of the tractor's tracks. It is always recommended to exercise caution and assess the conditions on-site before attempting to drive a heavy vehicle through challenging terrain.

I hope this helps! Let me know if you have any further questions.
