Question

Определите, какой высоты кирпичную стену можно построить на песчаном грунте который выдерживает давление 35280Па. Плотность кирпича 1800 кг/м3

Answer 1

P=pgh
h=p/pg=35280/10*1800=1.96 м

Answer 2

Determining the Maximum Height of a Brick Wall on Sandy Soil

To determine the maximum height of a brick wall that can be built on sandy soil, we can use the formula for pressure:

Pressure (P) = Density (ρ) x Gravitational Acceleration (g) x Height (h)

Given: - Pressure (P) = 35280 Pa - Density of brick (ρ) = 1800 kg/m³ - Gravitational Acceleration (g) = 9.81 m/s²

We can rearrange the formula to solve for height (h):

Height (h) = Pressure (P) / (Density (ρ) x Gravitational Acceleration (g))

Let's calculate the maximum height using these values.

Calculation

Height (h) = 35280 Pa / (1800 kg/m³ x 9.81 m/s²)

Result

The maximum height of a brick wall that can be built on sandy soil, which can withstand a pressure of 35280 Pa, with a brick density of 1800 kg/m³, is approximately 2 meters.
