MECHANICAL ENGINEERING SHORT NOTES
Hello And Welcome!
Mechnotes presents high quality handwritten short notes for various examinations of mechanical engineering which includes GATE, SSC JE, PSU, and ESE. Short notes are the ultimate weapons during the whole preparation. Many students usually do not come up with short notes and they suffer badly in the last few days or months before the examination. Short notes must be clean and error-free so that you can make the best use of that in limited time. It will help you in quick revision and boost your confidence. Here you will get mechanical engineering short notes with high-quality content.

And many basic terms, important formulas, and concepts are present in short notes.
Mechanical working processes are used to enhance the working properties of metals. Mechanical working reduces the voids present in metal and makes them denser. With the use of the mechanical working process, impurities present in metal get elongated and dispersed within the metal. This increases the strength of the metal.
Plastic deformation takes place in metals and it is achieved by a large amount of force & heat. Displacement of atoms takes place and caused deformation. There are many ways to do that.
In rolling, it is done by applying a large amount of force through rolls. In forging, it is done by hammer or press machines. In Extrusion, the material is extruded out between dies. These all impart great strength to metals and used for different applications.
The wastage of material in mechanical working processes is either negligible or very small and the rate of production is quite high. Hence these processes improve the economy of production.
In this short note, all important concepts and formulas are also present there. It will help you in steady quick revision and save your precious time so that you can practice more problems related to Metal Forming.
Always refer to standard textbooks for doubt.
There are a total 12 no. of pages inside that.
It is a platform for Mechanical Engineering students which provides you high quality handwritten short notes for various examination like ESE,GATE,SSCJE,STATE PSC And PSUs. Short notes helps you in quick revision of subjects and save your precious time.
