In fact, this Chinese floating train floats about two centimeters above the ground. The speciality is that there is no friction from the tracks. When the wheels of a vehicle with normal rubber wheels are filled with less wind, the resistance of the vehicle to those wheels increases, this has been known since childhood when we were cycling. That is, we know that it is difficult to ride a bike if the wheels are windy. This is called Rolling resistance.
Even though the steel wheels of a train have no rolling resistance, the friction due to the mass of a train is not small. The equation for friction is called F = μ(Miyu) x R. Where R denotes the latter reaction. For example, when you place a book on a table, it is silent. the book has a counter-effect, the opposite of the book’s load. This makes the book stand out.
What is Miyu (μ)
Here Miyu(μ) is a Greek letter. It shows the friction coefficient of a given surface. For example, the friction caused by a railway wheel colliding with a railroad is less than the friction of a car with rubber wheels on the tarmac.
This friction is minimal in a vehicle that slips on snow. That is the coefficient of friction decreases. But if the wheels do not collide, the coefficient of friction can be eliminated. The Chinese floating train starts to lift and float above the ground for a few minutes, thus eliminating the surface friction. There is no friction when F = μ x R when μ is 0.
Speed of the floating train
Here is a Chinese floating train made using this method. The bullet train is named because of the speed of a mouse. Magnetic levitation is lifted off the railway lines. Its speed is 373 miles per hour. That is 597 kilometers per hour.
In other words, it is much faster than a skyscraper. If a flight from Beijing to Shanghai takes 4.5 hours, it takes only 3.5 hours for a person travelling on this train. You will never find someone who hasn’t played with the magnetic pieces in childhood. We know that opposite poles attract and repel similar poles. Anyone who has never experienced it can do it and understand it. This repulsive process is used on this Chinese floating train. China’s Railway Rolling Stock Corporation (CRRC) has designed a train called “Magnetic Levitation” and is scheduled to run in 2021.
Although not so fast, variants of this train have been used in China since 2003. The shape of the new train is designed to minimize air resistance.
