Question

Лед на реке выдерживает максимальное давление в 70кПа выдержит ли лёд если по нему пройдет трактор массой 5200кг и с площадью гусениц 1.2 м

Answer 1

Сначало умножим 5200Кг На 10н/кг= то получится 52000
Потом делим 52000 на 1/2м^2 Получилось 43344Па
Потом 70000Па больше 433444 То соответствено выдержит

Answer 2

F=5200кг*10Н/кг=52000Н
р=52000Н/1,2м²≈43333Па
70000Па>43333Па
Выдержит

Answer 3

Calculating the Pressure Exerted by the Tractor on the Ice

To determine if the ice will withstand the pressure exerted by the tractor, we can calculate the pressure exerted by the tractor on the ice using the formula:

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

Where: - Force (F) = Mass (m) * Acceleration due to gravity (g) - Area (A) = Area of the tractor's tracks in contact with the ice

Calculating the Force Exerted by the Tractor

The force exerted by the tractor on the ice can be calculated using the formula:

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

Given: - Mass (m) = 5200 kg - Acceleration due to gravity (g) = 9.81 m/s^2

Let's calculate the force exerted by the tractor on the ice:

Force (F) = 5200 kg * 9.81 m/s^2

Calculating the Area of the Tractor's Tracks in Contact with the Ice

The area of the tractor's tracks in contact with the ice can be calculated using the formula:

Area (A) = Length (l) * Width (w)

Given: - Length (l) = 1.2 m - Width (w) = Not provided in the search results

It seems that the width of the tractor's tracks is not provided in the search results. Without this information, it's not possible to calculate the exact area of the tractor's tracks in contact with the ice.

Conclusion

Without the width of the tractor's tracks, it's not possible to accurately calculate the pressure exerted by the tractor on the ice. Therefore, it cannot be determined whether the ice will withstand the pressure exerted by the tractor based on the information provided.
