Machine:

A machine is a tool containing one or more parts that uses energy to perform an action. Machines are usually powered by mechanical, chemical, thermal, or electrical means, and are often motorized. The power tool also required moving parts to classify as a machine. The advent of electronics has led to the development of power tools without moving parts that are considered as machines.

Classification of Machines:

There are different categories of machines.They include:

1.Simple Machine:

The simple machine is a machine that can be broken down into simple movable elements..Such as pulley, lever, screw etc.
2.Mechanical machine:

The word mechanical refers to the work that has been produced by machines or the machinery. It mostly relates to the machinery tools and the mechanical applications of science. Some of its synonyms are automatic and mechanic.

3.Electrical machine:
Electrical means operating by producing electricity, or concerned with electricity. An electrical machine is the generic name for a device that converts mechanical energy to electrical energy, converts electrical energy to mechanical energy, or changes alternating current from one voltage level to a different voltage level.

4.Electronic machine:

Electronics is the branch of physics, engineering and technology dealing with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes and integrated circuits, and associated passive interconnection technologies.

Types of Machines:

There are different types of machines available based on the purpose or field in which they are used. They include:

1.Heavy machines
2.Light machines
3.Access machines
4.Miscellaneous
5.Construction machines

1.Heavy machines:

Heavy equipment is what they use to excavate land to build buildings or roadways…such as high lifts, backhoes, bulldozers and excavators etc,.

2.Light machines:

Light machines are also used for all purposes such as in constructions, forestry and industries etc,.

3.Access machines:

The access machines are used machines where the resellers sell the used machines which are in good working conditions.

4.Miscellaneous:

The miscellaneous equipment means a variety of or many kinds of equipments that is used for different purposes.

5.Construction machines:

Heavy power machines that which perform specific construction or demolition functions are called as construction machineries There are different types of constructions and construction machineries. Such as

1.Road construction machines.
2. Building construction machines.
3.Tunnel construction machines.
4.Bridge construction machines.
5.Dam construction machines etc,.
