What is a pressure body? How to draw a cross-section of the pressure body? As follows:
(1) A body of pressure consists of three parts:
The surface itself; the liquid surface or an extension of the liquid surface; and the plumb planes of the four peripheries of the surface toward the liquid surface or an extension of the liquid surface.
(2) Drawing a cross-section of a body of pressure Note:
Step 1: Draw the surface line itself;
Step 2: Make plumb lines from the upper and lower edges of the surface wall (or the left and right edges) to the water surface line or its extension;
Step 3: Close the figure by the water surface line or its extension;
Step 4: Orient the body of pressure to be the direction of the surface The upper part is pressurized in a downward direction; the lower part is pressurized in an upward direction.
The volume that generates pressure on the surface of an object due to the weight of the liquid is called a pressure body. As shown in the figure, pressure bodies are further divided into real and imaginary pressure bodies. The pressure generated by a real pressure body acts vertically downward on the surface of an object, while the pressure generated by an imaginary pressure body acts plumbly upward on the surface of an object.
The following are some of the applications of the pressure body:
1, industrial automation control: pressure sensors are widely used in the field of industrial automation, real-time detection of the pressure state of the industrial production process, and used to control and regulate industrial equipment. For example, automated robot welding in the automotive manufacturing industry requires host and source type pressure sensor linkage control.
2, the field of health care: pressure sensors integrated into prosthetic limbs and wheelchairs and other medical equipment, can provide disabled people with more personal needs of comfort and use.
3, the automotive industry: in the automotive field, pressure sensors are generally used to detect the pressure of the tires, to provide the electronic system with the pressure data of the wheels, so as to ensure the stability and safety of the car.
4, the field of sporting goods: pressure sensors are also widely used in sports equipment, such as sports shoes embedded sensors can be real-time measurement of changes in the center of gravity of the human body and feedback to the athlete, in order to adjust the support of the feet as well as to improve the posture of the body and other factors, to enhance sports performance and practical skills.
5\ Construction and civil engineering: pressure sensors are also widely used in construction and civil engineering. They can be used to detect the stability and safety of buildings in natural disasters such as earthquakes and storms, and to assist relevant authorities in taking timely rescue measures.
