Merits and Demerits of Magnetic Bearings:

With the rapid growth of industrialization, the product bearing plays an important role for such development. It is one of the major parts of the machine. It is a device that allows the continuous movement of two parts of the machine. Generally all kinds of machines use them for the function of providing support to a rotational object.

There are various types of bearings. The magnetic bearings are not so popular as the ball and roller bearings. Reluctance force and Lorentz force are the two types of magnetic forces that are used in the magnetic bearings. They usually support the load with the help of magnetic force. They are used in particular places like in natural gas pipelines, petroleum refineries, etc. Magnetic bearings have certain merits of their own. They have no maintenance cost. They do not require lubricants as there is no surface wear and tear. They have long durability as compared to others. They are highly resistive and can be used for sensitive applications. Besides those merits they also have certain demerits. They are expensive as they require lot of time and effort for development. Assembling them in the machines is difficult.

The identity of the vehicle – Car Registration Plates

Car Registration Plates are very important for the vehicles. It is said to be the identity of the vehicle and it helps the government authorities to detect the suspicious vehicles. Car Registration Plates are registered with different but specific sequence of numbers and alphabets and they are also noticed by the area code; like from which area does the vehicle belong to. All these specified areas have their own code and identities which must be written on the number plates. The sequence of the number continues till its last specified number given by the main authorities.

When a selected number sequence is registered then the sequence of the numbers reverses and the alphabets along them also changes and the given number of vehicles gets registered. Car Registration Plates are very important for the vehicle and it must be on both sides like on front and back side of the vehicle as it helps in identifying the vehicle by the police department. The number plates always consist of six characters and it also helps in identifying the age of the vehicle. Car Registration Plates carry different number and alphabet sequences from each other and this is a major reason which makes the identity of the vehicle different from each other.
