Question

пол на веранде может выдержать давление, не превышающее 5,8 Па. Сможет ли такой пол не сломаться и выдержать давление круглого стола массой 12 кг, опирающегося на 5 ножек, площадь опоры каждой из которых равна 4 м2

Answer 1

Ответ:

Не сможет

Объяснение:

Дано:

p₀=5,8 Па

m=12кг

S=5*4м²=20м²

g=9,8Н/кг

________

p₀>p-?

Решение:

p=F/S

F=mg=12кг*9,8Н/кг=117,6Н

p=117,6Н/20м²=5,88Па

p₀<p т.к. 5,80 Па<5,88 Па => пол не выдержит давление стола и сломается

Answer 2

Can a floor on a veranda withstand a pressure of 5.8 Pa and support a round table weighing 12 kg, resting on 5 legs, each with a contact area of 4 m²?

To determine if a floor on a veranda can withstand the given pressure and support the weight of the table, we need to consider the load-bearing capacity of the floor and the distribution of weight on the legs.

Load-Bearing Capacity of the Floor: The load-bearing capacity of a floor depends on various factors such as the material, construction, and design. Without specific information about the floor's characteristics, it is difficult to provide a definitive answer. However, typical veranda floors are designed to support the weight of furniture and people, so they are generally capable of handling moderate loads.

Pressure Calculation: To calculate the pressure exerted by the table on the floor, we can use the formula:

Pressure = Force / Area

Given: - Force (weight of the table) = 12 kg - Area (contact area of each leg) = 4 m²

Let's calculate the pressure exerted by the table on the floor:

Pressure = 12 kg / (5 * 4 m²)

Pressure = 0.6 kg/m²

The pressure exerted by the table on the floor is 0.6 kg/m².

Comparison with the Given Pressure: The given pressure is 5.8 Pa, which is equivalent to 0.058 kg/m². Comparing this with the pressure exerted by the table (0.6 kg/m²), we can see that the pressure exerted by the table is significantly higher than the given pressure.

Therefore, it is likely that the floor on the veranda may not be able to withstand the pressure and may be at risk of breaking or getting damaged under the weight of the table.

Please note that this is a general analysis based on the given information. It is always recommended to consult a structural engineer or a professional to assess the specific load-bearing capacity of the floor and ensure its safety.
