Types of steel structure

U bolt and Straight bolt forming process

This is the simple process of making 2 types of bolt which is commonly used in our daily routine. It is also called as temporary assembly process. Using three types of tools, chamfering, threading and grinding (if required) are done. This process can be done using bench lathe for small rate of production. For mass production, multiple cnc and vmc are used. The process in this image consist of removing bolts and nuts and it is utilised to reduce the assemble time in the manufacturing process.

Explosive Welding

Explosion welding, also called as explosive cladding, joins two metals together by an explosive force. It is often used to join dissimilar metals that have a significant difference in mechanical properties, thermal expansion coefficients, or melting temperatures — such as a low-cost metal to a more expensive corrosion-resistant metal. Some of the common clad layers deposited onto the steel plate are aluminum, copper, bronze, titanium, monel, nickel alloys and zirconium.

Colour based reflectors

Colour based reflection is process which takes place due to the rate of absorbtion of the colour coated materials. Colour coating helps to control the heat of the sourroundings. Red color has the higher rate of reflection and the aluminium foil has lesser reflections. 

This colour is completely based on metals. If you are coating the metals, kindly consider this criteria.

Steel Making Process

Benefits of eating fruits

This image shows some of the benefits of eating fruits. 

Fruits are rich in vitamins and minerals that helps us to lead a healthy life. They reduce the risk of many diseases and are naturally low in calories. They are rich in fibre and so they help to maintain the gut health. Fruits have rich sources if they are eaten as raw rather than in the form of juice. Fruits alone are not enough to maintain a healthy body, however it is one of the main elements to maintain our health.

Drip Irrigation System

This image shows the components of Drip Irrigation system. 

Drip Irrigation system is sometimes called as trickle irrigation. It involves dripping the water at low rates in to the soil. Water is dropped directly on the soil close to the plants so that only the roots get wet. This increases the level of moisture in the soil and becomes a favourable condition for the plants to grow. This system have mainlines, sub-mains and lateral lines with emission points spaced along their lengths and through drippers water is delivered to the crops.

Herbs to control cholesterol

This image shows the list of some of the herbs which helps to reduce the level of cholesterol. 

High levels of Low Density Lipoproteins (LDL) cholesterol can increase the risk of heart disease. Daily diet plays an important role in maintaining our health. The natural herbs shown in the image can reduce the level of cholesterol. They have to be consumed in natural form to achieve the health goals.

Pond Aeration System

Pond aeration is the process of increasing oxygen in a pond to improve the quality of water. This results in allowing fish, aquatic insects, and aerobic bacteria to decompose non-living organic matter in the pond. 

Pond aeration increases the process of oxidation. This system works on the basis of special equipment called aerators. Dissolved oxygen is added to the pond which improves water quality and allows aerobic bacteria to decompose organic matter which naturally reduces pond weeds.

Air-purifying plants

This image shows the filters of air-purifying plants. 

There are various benefits of using indoor plants. They produce oxygen, remove toxins, purify the air, decrease the stress, foster the positive vibes, create a relaxed environment, and enrich health and well-being. 

Spider plant absorbs carbon monoxide, formaldehyde and xylene. Peace Lily can absorb xylene, formaldehyde and ammonia. Snake plant cleans air better than any other indoor plants. 

These remarkable plants need low maintenance as they just need little light and water. Avoid overwatering to these indoor plants.

Impact of climate change

This image shows the impact of climate change in health. 

Increase in air pollution paves way for asthma and cardiovascular disease. Due to extreme weather conditions, water-borne diseases such as cholera, leptospirosis and so on may occur. This may also leads to respiratory allergies. In addition to it, vector-borne diseases such as Malaria and dengue may also occur. 

As a result of increasing sea level, infections may spread through water and food supply. This leads to malnutrition, diarrhoea and harmful algal blooms. Hence, steps must be taken to prevent the worst impacts of climate change.

Crop rotation

This image shows the rotation of crops.

Crop rotation is growing different types of crops in the same area. This reduces the reliance on one set of nutrients, reduces weeds, problems with insects, and also the development of pests. 

Planting same crops in the same place may deplete the amount of certain nutrients in the soil and so crop rotation is essential. These rotations are also helpful in controlling corn rootworm, nematodes and diseases like root rot of field peas.

Working of Tape recorder

This image shows the working of tape recorder. 

Tape recorder is the first ever recorder for audio singals using tapes which consists of strips of data storage. Some specific microphones help to record the audio of the sound source which is converted into digital signals through audio amplifier. It is then stored in the tape again and audio amplifier from the tape helps to give sound output to the speaker. It receives recording and sends the audio signals.

Types of transformer

This images shows the different types of transformer.Transformer is a device helps to reduce and increase the voltage as per the requirement of power in any particular area. Transformer is working on the basic principle of electromagnetic induction through which an AC current passes through a coil and generates electro magnetic force ( emf ) which helps to induce the another coil. Hence the voltage of the second coil is controlled by using power supply of the first coil. The distribution transformer is found in a particular street or area whereas power transformer is found in industrial area.

Types of mobile camera

This image shows the types of camera in mobile phone. 

Ultra wide camera helps to cover a wide angle with 120° from the vision point of camera. This is working based on our human eye movements at a maximum of 123°. It helps to cover wide distance but it do not focus as much telephoto camera. 

A telephoto lens, in photography and cinematography, is a specific type of a long-focus lens in which the physical length of the lens is shorter than the focal length. The angle of view and other effects of long-focus lenses are the same for telephoto lenses with the same specified focal length.

The Depth Vision camera is a Time of Flight camera in some of the mobile phones. It judge the depth and distance and makes the photo to high standards. It measures the distance using the speed of light by counting the time taken for the reflected beam to reach the sensor.

Functions of bacteria

This image shows the uses of harmless bacteria. 

Some bacteria lives in our body are harmless. They are helping us in many ways. Some of them are discussed below-

They promote the storage of fat and develop the immune system. They promote angiogenesis and modulate the bone-mass density. Bacteria acts as a protection against epithelial injury and also give resistance to pathogens. They break down the food compounds and help in modifying the nervous system. It assists in the metabolism of therapeutics and in the biosynthesis of vitamins, amino acids etc.

Multi camera system stimulation

This image shows the stimulation of multi camera system. 

MATLAB stimulation helps to develop new software which solve the multi disciplinary problem. The process of logical system and experiment system are explained separately and it shows the working of MATLAB.

Fibre optic communication system

This image shows the basic fibre optic communication system. 

This communication system is one of the recent developments in technology. Electrical signals/digital signals are converted in to light signals using fibre optic cables. This cable consists of optical reflector and transmitter. With these components, the data source is transferred within microseconds. 

Signals from input data are sent to the transmitter circuit. Using fibre optic cable, light source is transferred to the detector. Receiver circuit collects the source and it converts them in to digital data again.

Production of organ-humanised mouse

This image shows the production of organ-humanised mouse. Let us know about the application of genetic engineering for tests using mouse. Recent tests for COVID-19 vaccination has also been undertaken on mouse. 

There is a rapid improvement on genome analysis technology. Research on diseases that are associated with genes are also being done. However, there is always an obstacle between Gene and disease, since humans cannot be used as an experimental object.  Hence, model animal is taken as an experimental object which plays an important role. 

An innovative technology becomes essential to cope up the difference between humans and animals, both genetically and phenotypically. "Humanised mouse" becomes the solution to this problem.

Aluminium production process

This image shows the production process of aluminium. 

Aluminium is the most effective and desirable material. It is a natural gift from the nature. Once aluminium was discovered, it took the position of other metals such as copper, silver and steel type materials.

Aluminium is manufactured from the raw material called alumina which is in liquid form. It is allowed to flow through furnace and it is converted into high reactive liquid aluminium. 

As per our requirement, the process of shaping the metal can be done such as using metal extrusion process in a rod, using sheet metal through cutting or by using wire rod by rolling it.

Basic Marking Methods in machining

The above image indicates the four process such as Engraving,Marking,Fusing and cutting are the most commonly used marking methods in laser based machiningprocess.Engraving is the process of removing the material based on the logo,designs and naming of the industry with respect to the products.

Marking is mostly based on the process of numbering for identification which won't be visible at the end result of the product.Fusing refers to the process of heating and melting of 2 material based on the requirement which is similar to welding process.

Cutting is almost common machining process once the marking step is completed separation of each parts done by cutting process.

All the process can be concurrent and also a seperate work based on the requirement of the product.

Crescograph

This image is a device to detect the plant growth. 

It is device used for measuring the height of the plant from 0.0001 inch to 0.000001 inch of precision. It helps in the research that are based on plants anatomy and its natural behaviour based on the climate change. It also helps to detect the longlasting life period of the plants depending upon its height. 

However, its normal operating range is from 1/1000 to 1/10,000 of an inch. The component which actually measures the movement is a differential transformer (A). It's movable core is hinged between points (B) and (C). Two lever arms hinged at points (D), (B) and (E), (C), form a parallelogram that holds the core centered within the opening of the differential transformer as it moves up and down. A micrometer (F) is used to adjust and calibrate the system. This device was invented by the Indian scientist Jagdish Chandra Bose.

Manufacturing flow of Nut

This image shows the manufacturing flow of nut.

A steel wire rod is straightened using a forming machine. Using a cutting machine, the rod is cut and the pieces are heated at 1200°C using induction heater. 

Using hydraulic hammer, head of the nut is made and it is drilled with drilling machine and lubricant oil. It is then threaded using threading machine and again heated at 870°C for one hour with induction heater. After this rapid cooling is done using oil chamber. As a result, finished nut is obtined.

Components in microphone

This image shows the material composition of microphone. 

Microphones are also called as mic which is an electronic device that converts sound waves to electrical signals using magnets, coils and wires. The outer shell of this device is made up of plastic material which acts as an insulator. Diaphragm is a clothing structure that has infinite holes which allow the sound waves for the equal distribution of signals. This simple principle is to convert vibrations to electrical signals which is the reverse piezo effect.
