To increase popularity and foster technical exchanges among sea enthusiasts, 【Question of the Day】 is launched. Participation earns 4 points of wealth! 10 wealth points as a reward for correct answers or in-depth discussions! :lol Question: What is “stress”? Answer: Pressure is the force that acts perpendicularly on the surface of an object. ============================= Promotion of petrochemical activities: ☛Notice on the launch of the large-scale event “I’m saving energy; where are you?” in the petrochemical area: http://bbs.hcbbs.com/thread-1579199-1-1.html (Source: Haichuan Chemical Industry Forum). This event offers awards in both text and image categories. When there are over 200 entries, an additional grand prize will be awarded, worth 600 Haichuan coins; if there are more than 300 entries, the grand prize value increases to 1,000 Haichuan coins, and for 500 entries it rises to 1,500 Haichuan coins. First prize: 3 Haichuan commemorative water cups; second prize: 5 winners, each receiving 120 Haichuan coins; excellence awards: several winners, each receiving 200 Haichuan coins. --------------------------------------------------------------- ☛“My plant, my home” – Photo competition (10 Haichuan coins per photo): http://bbs.hcbbs.com/thread-1495069-1-1.html (Source: Haichuan Chemical Industry Forum)
Pressure: The force acting per unit area vertically on a fluid or solid interface.
A force that acts perpendicularly on the surface of an object is called pressure, and its unit is newtons per square meter.
The force acting on the contact surface between two objects; in engineering, pressure and stress are synonymous
Pressure is a force that acts perpendicularly on the surface of an object.
The force per unit area acting vertically on the interface between a fluid and a solid.
Pressure: The force that acts per unit area on the interface between a fluid and a solid. The interface can be any dividing surface within a fluid, or it can be the contact surface between a fluid and a solid. The surface of any fluid element is subject to forces from the outside environment; these forces are known as surface forces.
In physics, pressure refers to the force that acts on the contact surface between two objects, or it is the vertical force exerted by a gas on the surface of a solid or liquid, or the vertical force exerted by a liquid on the surface of a solid. *Conventionally, in mechanics and most engineering disciplines, the term “pressure” is synonymous with pressure in physics. For elementary school students, if a teacher asks them to write 100 essays over the summer vacation, this is considered “stress”.
Pressure is motivation; that’s what teachers often say in school
It refers to the force acting per unit area vertically on the interface between a fluid and a solid
Pressure, from a microscopic perspective, is explained by the movement of molecules; it is often illustrated by gas molecules colliding with the walls of a container. Macroscopically, pressure is described using mechanical analysis, namely Newton’s laws.
