Question

СРОЧНО ДАЮ 15 БАЛЛОВ Вес шкафа равен 11 кН. у шкафа четыре ножки. площадь опоры каждой ножки равна 100 см². какое давление оказывает шкаф на соответствующую поверхность( при необходимости ответ округлите до целого числа )Давление ровно: ... кПа

Answer 1

Ответ: 275кПа

Объяснение:

Дано:

Р=11кН=11000Н

S1=100cм²=0,01м²

n=4

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

р-?

р=Р/S=P/4S1=11000/(4*0,01)=275000Па=275кПа

Answer 2

Calculation of Pressure

To calculate the pressure exerted by the cabinet on the corresponding surface, we need to divide the force exerted by the cabinet by the area of the surface.

Given: - Force exerted by the cabinet (weight of the cabinet) = 11 kN - Number of legs supporting the cabinet = 4 - Area of each leg = 100 cm²

To find the pressure, we can use the formula:

Pressure = Force / Area

Let's calculate the pressure:

Force exerted by the cabinet = 11 kN

Area of each leg = 100 cm²

Number of legs = 4

Total area of all legs = Area of each leg * Number of legs

Total area of all legs = 100 cm² * 4 = 400 cm²

Now, let's convert the area to square meters for consistency:

Total area of all legs = 400 cm² = 0.04 m²

Using the formula, we can calculate the pressure:

Pressure = Force / Total area of all legs

Pressure = 11 kN / 0.04 m²

Calculating the pressure:

Pressure = 275 kN/m²

Therefore, the pressure exerted by the cabinet on the corresponding surface is 275 kPa (rounded to the nearest whole number).
