Science of Machines

The subject Science of Machines is that subpart of Engineering, which deals with the study of relative motion among the various parts of a machine, along with forces that act on them.

The knowledge of this subject is very helpful for a person to design the numerous parts of a machine.

What is a machine?

A machine is a mechanism or a combination of mechanics that, apart from imparting definite motions to the parts, also transmits and modifies the available mechanical energy into some kind of desired work.

Nowadays, our urban landscape is littered with these towering tools of construction, often seen as a precursor to renewal and development.

Well, 2,500 years ago, cranes were used in a very similar fashion and helped changed the face of society, turning it from agrarian to industrial.
It’s believed they were invented by the ancient Greeks around the late 6th century BCE and were also used to lift massive loads for their building of temples, government buildings, and canals.

Although the 24-hour day is something almost inconceivable to imagine living without, that’s exactly what humans did before the introduction of the mechanical clock—and the first public clocks—in the late 13th century.

Although water clocks had existed for millennia, the mechanical clock was the first reliable time-keeping device that allowed Western society to transition from the fluid “canonical” hours instituted by the church to the 24 hour day.

This concept became fully embraced by merchants as a reliable way to do business (which is why so many early clocks show up in Italian towns), and the mechanically monstrous clock towers soon helped synchronize human activity for the first time.

In my belief, the most fascinating part of mechanics is to have a challenge that involves the requirement to design and fabricate a production problem or even relieve workers from having to do work that is detrimental to their health.
