Question

Вес рабочего стола равен 41 КН у рабочего стола четыре ножки площадь опоры каждый ножки равна 16 см квадратных Какое давление оказывает рабочий стол на соответствующую поверхность? Ответ при необходимости округлите до целого числа Давление равно… кПа

Answer 1

Ответ: 6406кПа

Объяснение:

Дано:

Р=41кН=41000Н

S1=16см²=0,0016м²

n=4

========

р-?

р=Р/S=P/(4*S1)=41000*/(4*0,0016)=6406250Па=6406кПа

Answer 2

Calculation of Pressure

To calculate the pressure exerted by the desk on the corresponding surface, we need to divide the force (weight) exerted by the desk by the area of the supporting surface.

Given: - Weight of the desk = 41 kN - Number of legs supporting the desk = 4 - Area of each leg = 16 cm²

To find the total area of the supporting surface, we need to multiply the area of each leg by the number of legs: Total area of the supporting surface = Area of each leg * Number of legs

Let's calculate the total area of the supporting surface first: Total area of the supporting surface = 16 cm² * 4 = 64 cm²

Now, we can calculate the pressure exerted by the desk on the corresponding surface: Pressure = Weight / Area

Converting the area from cm² to m²: Total area of the supporting surface = 64 cm² = 64 cm² * (1 m² / 10,000 cm²) = 0.0064 m²

Now, let's calculate the pressure: Pressure = 41 kN / 0.0064 m²

To round the answer to the nearest whole number, we can use the appropriate rounding method. In this case, we will round to the nearest whole number.

Please note that the search results did not provide the conversion factor for kilonewtons (kN) to kilopascals (kPa). To proceed with the calculation, we will assume that 1 kN is equal to 1 kPa for simplicity.

Using this assumption, we can calculate the pressure exerted by the desk on the corresponding surface:

Pressure = 41 kN / 0.0064 m² = 64062.5 kPa

Rounding this value to the nearest whole number, the pressure exerted by the desk on the corresponding surface is approximately 64063 kPa.

Please keep in mind that this calculation assumes a simplified conversion factor between kilonewtons and kilopascals. If you require a more precise conversion, please consult a reliable engineering resource.
