2. “Physics in the profession of auto mechanic”

2.Introduction.

One of the most necessary professions of our time is the profession of an auto mechanic.

Road transport plays an important role in providing passenger and freight transportation. The world's car park is expanding every year, and a car mechanic is for a car like a doctor is for a person: he treats and carries out preventive measures. And in an accident, one of the reasons is simply a malfunction of the car.

6) Fundamentals of mechanics, thermodynamics, heat engineering.

4. Physics in the design of a car

The car is literally packed with advances in physics:

For example, the operation of an engine is carried out thanks to the law of thermodynamics: gas produced by combustion of fuel expands and moves the piston.

A) Maintain electrical safety.

When working with 220-380 Volt equipment, use rubber gloves, a mat, and watch

The insulation is in good working order and the humidity in the rooms should not exceed 60%.

B) For welding and drilling work protect your eyes from chips and light with a shield,

Wear gloves and protective clothing and, if possible, a respirator

B) When working with a battery and a soldering iron have protective equipment on hand

Exposure to acids

D) When working with lifts and jacks install safety trestles.

19. Auto mechanic is a necessary profession! It is impossible for an auto mechanic to work without knowledge of physics. Physics

Plays a major role in the profession of auto mechanic.

Physics is the science of nature in the most general sense. She studies mechanical, electrical, magnetic, thermal, sound and light phenomena. Physics is called “fundamental science.” Therefore, its laws are used in almost all areas: medicine, construction, all areas related to technology, electronics and electrical engineering, optics, astronomy, geodesy, etc.

Physics in construction

Building physics studies in detail the phenomena and processes associated with the construction and operation of buildings and structures. These phenomena and properties are characterized by physical quantities. Construction activity is inextricably linked with certain environmental conditions: temperature, humidity, air composition, density of matter.

First you need to study the area where construction will take place. This is what surveyors do. Engineering geodesy studies methods and means of geodetic work in the design, construction and operation of various engineering structures. Geodesy problems are solved on the basis of the results of special measurements performed using geodetic instruments, since it is necessary to evaluate the site of the proposed construction. it is necessary to obtain information about the terrain. All these calculations serve as the basis for the design of structures and buildings. And here you can’t do without the laws of physics!

Physics in the profession of Architect

The profession of an architect involves architectural design at a professional level. The specialist’s responsibilities include organizing the architectural environment, designing buildings and developing space-planning and architectural solutions.

In architecture, the laws of physics are of great importance, which help to consider the role of the concepts of STABILITY, STRENGTH, RIGIDITY OF STRUCTURES, as well as the role of floors and foundations in the construction of buildings, deformation of structural elements and calculations. Using the laws of statics when

Physics in the medical profession

Currently, the line of contact between physics and medicine is extensive, and their contacts are constantly expanding and strengthening. There is not a single field of medicine where physical instruments are not used to identify diseases and their treatments.

The most important part of the human body is the circulatory system. The action of the human circulatory system can be compared to the operation of a hydraulic machine. The heart works like a pump that pushes blood through the blood vessels. When the heart contracts, blood is pushed out of the heart into the arteries and passes through valves that prevent it from flowing back into the heart. Then it relaxes and during this time it fills with blood from the veins and lungs. The discovery of simple ways to measure blood pressure has made it easier for doctors to recognize diseases that indicate abnormal blood pressure.

Physics in the profession of a cook

Very important branches of physics for a chef are molecular physics and thermodynamics. As they say, a good result cannot happen by chance... So, to cook a good steak, you need to put it in a hot frying pan and add a small amount of fat or oil.

The oil will plug the holes in the meat and it will cook juicy.

Physics in the photography profession

The profession of a photographer is closely related to the science of Physics.

Concepts such as focus, lens, etc. belong to this profession.

The main element of the equipment is the lens. Without it, there would be no microscope, no telescope, no glasses... And this means that many people over 50 could not read, biologists could not study the cell, and astronomers could not study space.

Physics in the profession of nuclear engineer

Here physics is used to solve problems of nuclear energy enrichment.

Nuclear physicists, together with atomic physicists, study the structure of the atom and the processes in it and often make great discoveries.

Physics in the profession of petroleum engineer

The use of internal combustion engines, the development of mechanical engineering, and the aviation industry became possible with the discovery of more and more oil fields. Huge oil reserves allow the development of industry.

In this profession, researchers are discovering new ways to improve oil and natural gas production.

Physics in mechanical, aviation and rocket engineering

A designer of rockets, space stations, satellites, anti-missile systems must know physics and understand the essence of physical processes...

Informatics and computer technology specialist

In modern life, a lot of information technology tools have appeared with which you can create presentations for lessons, recreate experiments and scientific discoveries of ancient scientists, and all this with the help of animation, raster and vector graphics, and video. All these methods make life much easier for modern teachers and lecturers.

The impulse turns into numbers, numbers into binary code... that's why physics is present in computer science.

Physical phenomena are an integral part of the world around us, which is based on the laws of this science. Therefore, it is not at all surprising that any profession, whatever it may be, is somehow connected with physics.

I want to become a doctor in the future. For this profession, subjects such as chemistry and biology are of paramount importance, which is why applicants take them when entering a medical school. But physics is also far from the last place for a doctor.

This science underlies the functioning of many body systems. Thus, our heart in combination with blood vessels is nothing more than a biological pump, on the work of which, for example, human blood pressure depends. We perceive visual information with the help of our visual organs, and the lens located inside each eye acts as a biconvex lens that refracts light.

Based on the laws of such a branch of physics as optics, not only our eyes work, but also many medical equipment. First of all, these are microscopes necessary for studying the structure of human body tissues and microorganisms.

X-ray machines and magnetic resonance imaging scanners, which are used in clinics to study the state of human internal organs, are also equipment whose operation is determined by knowledge of the principles of various physical processes. Ultrasound also became possible only after the discovery of high-frequency sound waves (ultrasound).

Physics is of particular importance for dentistry. In the future, I want to become an orthopedic doctor and install dental prosthetic structures, so understanding the various properties of solids and studying the laws of mechanics is very important to me. Without this knowledge, I will not be able to work in my chosen profession, and therefore, even now, while studying at school, I am doing everything possible to master a difficult, but so necessary science for a doctor.
