TO DESIGN A MACHINE THEORY PART NEEDED

 Machine Element Design is the application stage after the theory (Engineering mechanics, solid mechanics, Theory of machines, Theories of failure etc.), I'll say that it is the crucial stage of 'connecting the dots'. All that you learned in the previous courses might have come out arbitrary and dispersed, but this is the stage where you recognize those 'patterns' in a system and apply those concepts. It is like an archaeologist stepping into the pyramids. It's that fascinating stuff. So my advise would be that FIRST recall the theory part in case you've forgotten. That is to say: get your tools ready else you'll lose patience/interest as you can't recall in middle of the problems. You don't want to go all the way back to your research lab to get the tools! Now, find a quite place like library that gives an atmosphere for the job. And then, start decoding the inscriptions i.e. looking for patterns and connecting the dots!

Pascal's calculator

A Pascaline, signed by Pascal in 1652

Pascal's calculator is a mechanical calculator invented by Blaise Pascal in the early 17th century. It was called the arithmetic machine and later became known as the Pascaline. Pascal was led to develop a calculator by the laborious arithmetical calculations required by his father's work as supervisor of taxes in Rouen.^[1] He designed the machine to add and subtract two numbers directly and to perform multiplication and division through repeated addition or subtraction.
Pascal's calculator was especially successful in the design of its carry mechanism, which adds 1 to 9 on one dial, and when it changes from 9 to 0, carries 1 to the next dial. His innovation made each digit independent of the state of the others, which enabled multiple carries to rapidly cascade from one digit to another regardless of the machine's capacity. Pascal was also the first to shrink and adapt for his purpose a lantern gear, used in turret clocks and water wheels, which could resist the strength of any operator input with very little added friction.
Nine Pascal calculators have been made,^[2] including the first surviving mechanical calculator from the 17th century. Most of them are on display in European museum

James Albert Bonsack's cigarette rolling machine, invented in 1880 and patented in 1881.

A machine is a tool containing one or more parts that uses energy to perform an intended action. Machines are usually powered by mechanical, chemical, thermal, or electrical means, and are often motorized. Historically, a power tool also required moving parts to classify as a machine. However, the advent of electronics has led to the development of power tools without moving parts that are considered machines.^[1]
A simple machine is a device that simply transforms the direction or magnitude of a force, but a large number of more complex machines exist.
