Today, I will talk to you about what p is and what is in f=ps. Many people may not know much about it. In order to make you understand better, the editor has summarized the following for you. I hope you can get something from this article.

F=PS is the pressure formula.

F refers to pressure, in Newton (N).

P means p for pressure, in Pascal (Pa), or (Newtons per square meter).

S is the compressed area, in square meters.

Related introduction:

Physical pressure refers to the force that occurs on the contact surface of two objects, either the vertical force of the gas on the solid and liquid surface, or the vertical force of the liquid on the solid surface. The force acting vertically on the surface of objects due to squeezing each other is called pressure. For example, the force of the football on the ground, the force of the body on the slope, the force of the hand on the wall, and so on. Traditionally, in mechanics and most engineering disciplines, the word "pressure" is synonymous with pressure in physics.

The direction of the pressure is perpendicular to the contact surface and points to the pressed object (note: the meaning of "vertical" is different from that of "vertical"). The condition is that the objects touch and squeeze each other.

Characteristics

1. The action direction is perpendicular to the action area and opposite to the outer normal direction of the action area.

two。 When the pressure is constant, the smaller the stress area is, the more significant the pressure effect is.

3. When the stress area is constant, the greater the pressure is, the more significant the pressure effect is.

Calculation formula

Pressure = pressure × stress area (F=pS).
