By machines, I remember, the definition of simple machines from my school days which was, 'Any device that helps in easing out the work of a human being is a machine. It could be a pulley, a screw or even a wedge'. The origin of these simple machines has been traced back to 3rd century BC by Archimedes, the famous Greek philosopher. Since then, there has been a huge development and machines have redefined themselves to become an integral part of our lives.
The modern machine can be defined as, “Any equipment that uses energy to perform some activity is called a machine”. If we look around, we are surrounded by machines of all sort, that have made our lives a lot easier. It doesn’t take a machine gun or a home generator to be called a machine! Anything as small and simple as a cell phone or a radio, to something as common as the microwave oven fall under the category of machines. Machines have several parts, which, when performing efficiently, help in achieving the goal they are meant to attain. We cannot imagine our lives without machines, as it is a not-so-mentioned basic necessity for us. You could probably use some of these machine quotations and sayings if you’re studying about them!
