Question

В одній посудині міститься твердий брусок, який не прилягає до стінок посудини, в другій шріт в третій - вода.Зобразіть графічно, як передаватиметься тиск цими тілами.

Answer 1

Объяснение:

Возникновение сил давления в жидкостях и газах и их направление. Попробуйте закрыть пальцем отверстие водопроводного крана – вы почувствуете силу, действующую на палец. При погружении даже на небольшую глубину, ваши уши испытывают неприятные ощущения. Эти примеры свидетельствуют о том, что в жидкостях действуют силы давления.

Как возникают силы давления в жидкостях? Сожмем жидкость, закрыв сосуд с жидкостью поршнем, а сверху положив груз (рис. 144). При этом каждый объем, выделенный внутри жидкости, будет сжат со всех сторон соседними объемами и из-за упругости с такой же силой будет действовать на них

Answer 2

Pressure Transmission in a Container

When a solid block, which does not fit tightly against the walls of the container, is placed in one vessel, and water is present in the second vessel, pressure is transmitted differently through these two substances.

The pressure in a fluid (such as water) is transmitted equally in all directions. This means that the pressure exerted by the water will be transmitted to all surfaces in contact with it, including the walls of the container and the solid block. The pressure transmitted by the water will act perpendicular to the surfaces it contacts.

On the other hand, the pressure in a solid object is transmitted only in the direction of the force applied to it. In this case, the solid block does not fit tightly against the walls of the container, so the pressure exerted by the block will not be transmitted to the walls of the container. Instead, the pressure will only be transmitted through the points of contact between the block and the container.

To illustrate this graphically:

1. The solid block will exert pressure only at the points where it is in contact with the container walls. These points of contact will experience a force perpendicular to the surface of the block. The pressure will be transmitted through these points of contact and will act perpendicular to the container walls.

2. The water in the second vessel will exert pressure equally in all directions. The pressure will be transmitted to all surfaces in contact with the water, including the walls of the container and the solid block. The pressure will act perpendicular to the surfaces it contacts.

Here is a graphical representation of how the pressure is transmitted by these two substances:

                Solid Block

In the diagram, the water is represented by the upper vessel, and the solid block is represented by the lower vessel. The arrows indicate the direction of the pressure exerted by each substance.

Key Points: - The pressure in a fluid is transmitted equally in all directions. - The pressure in a solid object is transmitted only in the direction of the force applied to it. - The solid block will exert pressure only at the points where it is in contact with the container walls. - The water will exert pressure equally in all directions.

I hope this helps! Let me know if you have any further questions.
