    What is solar system 

The solar system refers to the Sun and all the celestial bodies that orbit it. This includes eight planets, dwarf planets, moons, asteroids, comets, and other space objects that are all bound by the Sun's gravity. The eight planets in our solar system, in order from the Sun, are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. The study of our solar system is known as solar system astronomy.

Here are some of the important facts of solar system.

The Sun is the center of the solar system and contains over 99.8% of its total mass.
The eight planets in order from the Sun are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
Pluto was once considered a planet but is now classified as a dwarf planet.
The asteroid belt is located between Mars and Jupiter and contains millions of rocky objects.
Kuiper Belt is located beyond Neptune and contains many icy objects, including dwarf planets such as Pluto.
The Oort Cloud surrounds the solar system and is believed to contain trillions of comets.
The average distance between the Sun and Earth is 93 million miles or 150 million kilometers.
The speed of light is an important constant in solar system astronomy and is approximately 186,000 miles per second or 299,792,458 meters per second.
The astronomical unit (AU) is used to describe distances within the solar system. One AU is the average distance between the Sun and Earth, about 93 million miles or 149.6 million kilometers.
The period of revolution (orbital period) for each planet, or the time it takes to complete one orbit around the Sun, varies greatly. For example, Mercury takes 88 Earth days to orbit the Sun, while Neptune takes nearly 165 Earth years.
The solar system's age is estimated to be around 4.6 billion years old.

Angle beam transducers in ultrasonic testing.

Image
Angle beam transducers   :-Angle beam transducers and wedges are typically used to introduce a refrected shear wave into the test material. Transducer can be purchased in a variety of fixed angles or adjustable versions where the user determines the angles of incidence and refraction. In the fixed angle versions, the angle of refraction that is marked on the transducer is only accurate for a particular material,, which is usually steel. The angled sound path allows the sound beam to be reflected from the Blackwell to improve detectability of flaws in and around welded areas. They are also used to generate surface waves for use in detecting defects on the surface of component. Normal incident shear wave transducer: - are unique because they allow the introduction of shear waves directly into a test piece without the use of an angle beam wedge. Careful design has enabled manufacturing of transducers with minimal longitudinal wave contamination. The ratio of the longitudinal to sh...

Introduction of welding machine,

Introduction of welding machine, The history of welding machines dates back to the 19th century. Here is a brief overview of the development and evolution of welding machines: 1).     Carbon Arc Welding: In the late 1800s, Sir Humphry Davy discovered the process of carbon arc welding. This process involved creating an electric arc between a carbon electrode and the metal to be welded, resulting in the fusion of the metals. 2).     Resistance Welding: In the early 20th century, resistance welding became popular. This technique used electric current and pressure to bond metal parts together. Spot welding, seam welding, and flash welding are common methods of resistance welding. 3).    Arc Welding: The invention of arc welding in the early 20th century brought a major breakthrough in the field. This process involved using an electric arc struck between an electrode and the metal workpiece to create the necessary heat for melting and fusin...
