Question

Вес 50 кг,площадь 214 как найти давление 1)стоя 2)при ходьбе.

Answer 1

если весртравен силе тяжести.то нужно 50 разделить на 214

Answer 2

Calculating Pressure

To calculate the pressure, we can use the formula:

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

Given: - Weight (Force), F = 50 kg - Area, A = 214 cm^2

When Standing Still

When standing still, the force due to the weight acts perpendicular to the surface. Therefore, the pressure can be calculated as:

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

Substituting the given values: Pressure (P) = 50 kg / 214 cm^2

This gives us the pressure when standing still.

When Walking

When walking, the pressure may change due to the dynamic nature of the movement. The pressure exerted while walking can vary based on the gait, speed, and distribution of weight during the movement. However, for a simple approximation, we can consider the pressure exerted while walking to be similar to the pressure when standing still, as the change in pressure due to walking may not be significant for normal walking speeds and movements.

Therefore, the pressure while walking can also be calculated using the same formula:

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

Substituting the given values: Pressure (P) = 50 kg / 214 cm^2

This gives us an approximation of the pressure while walking.

Answer 3

Calculating Pressure

To calculate the pressure exerted by a person with a weight of 50 kg, we can use the formula:

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

Where: - Force (F) is the weight of the person in Newtons (N), which can be calculated using the formula: Weight (W) = Mass (m) * Acceleration due to gravity (g), where g is approximately 9.81 m/s^2. - Area (A) is the area in contact with the surface.

When Standing Still

When the person is standing still, the area in contact with the surface is the area of both feet. Assuming an average foot area of 214 square centimeters, we can calculate the pressure when standing still using the given weight of 50 kg.

First, let's calculate the force exerted by the person's weight: Weight (W) = Mass (m) * Acceleration due to gravity (g) W = 50 kg * 9.81 m/s^2

Now, we can calculate the pressure: Pressure (P) = Force (F) / Area (A)

When Walking

When the person is walking, the area in contact with the surface changes as the person's weight shifts from one foot to the other. This dynamic change in area affects the pressure exerted during walking.

The pressure exerted while walking can vary depending on the distribution of weight between the feet and the movement dynamics. However, the general principle remains the same: pressure is the force exerted per unit area.

In summary, the pressure exerted by a 50 kg person can be calculated using the formula for pressure, taking into account the area in contact with the surface. When standing still, the pressure is calculated based on the total foot area, while during walking, the dynamic changes in weight distribution affect the pressure exerted.
