What is Machine?

Machine is a tool containing one or more parts that uses energy to perform intended action. In simple language we can say that machine is a tool which simple our daily works. In our daily life everywhere we use machines for completing our works. For example, if we want to go office than we use car, bus, bike so many vehicles. So we are all connected with machines.

Machines are mostly powered by mechanical, chemical, thermal resources. A simple machines that simply transforms direction or magnitude of forces. But large numbers of complex machines are also exist.

Mechanical

The word mechanical refers to a work that is produced by machines or machinery. It is mostly refers to machine tools and related to its application in science.

Simple Machine

We can understand from the word that what is simple machine? Simple machine means machine which is not contain complex structure. Simple machine consist only simple structure. For example: Screw, Lever, pulley etc…

Engine

An engine or motor is designed to convert energy into useful works. We can easy convert energy into do our work. There are so many engines which are I have discussed above.

Electrical machine

  These kinds of machines are operating trough electricity. They convert electrical energy into mechanical energy or vice versa.

These all machines we use in our daily life. They are use to everywhere. Without machines we can‘t able to our work instantly…
