Essential softwares for mechanical engineers

Here are some softwares listed below :

1. AutoCAD ( A basic CAD software for design and drafting purpose)
2. Pro/Engineer ( A complete parametric 3D CAD/CAM/CAE software)
3. C Language (A programming language)
4. ANSYS ( An analysis or simulation software)

AutoCAD and its Capabilities  
AutoCAD is a drafting software which involves drawing of 2D objects as well as 3D modelling.

Importance of AutoCAD

Being a Mechanical student, one need to do final year project. It involves experimental/fabrication work or theoretical analysis. To understake any project, one need to use at least one software or more.

For experimental work, the components of parts should be fabricated with required dimensions. So, 2D or 3D drawing/models are required to be prepared in AutoCAD or in other drafting software. After creation of the drawing, printout/drawing-sheet of it must be given to fabricator who will create the component in physical form.

This procedure is same as performed in any design and manufacturing industries. The design department sends drawing to manufacturing department and manufacturer prepares mechanical component or system based on it. Thus, one should know how to draw, analyse and prepare drawings in AutoCAD. 

Pro/Engineer Capabilities

 Pro/Engineer is a complete Mechanical package of drawing, modelling and analysis. Pro/Engineer's design package includes 2D drawing, 3D models and assembly. Pro/Engineer also does functions like 2D CAD, 3D CAD, customization, Data exchange like IGES (Initial Graphics Exchange Specification) and other formats, Dynamics publishing, engineering calculations, Visualization and mock up etc.

C Programming Language 
Being a mechanical student, there is a great importance of C language because when you learn computational subjects, you need to use C programming to do the calculations for solution by numerical methods and most methods in computations are iterative as well as trial and error one. So, in programming by C, one can use loops, decision making, functions, arrays and file management to serve the purpose of solution of the numerical methods used for given problem's physics. There are plenty of programming languages are available but C is one of best among them. If you use MATLAB, it will require more memory but less skills, FORTRAN is also competitive to C but if you know C language, there is no need to learn other programming and if it is required to learn, you can learn easily as all programming languages are quite similar.

ANSYS for Finite Element Analysis

Finite Element Method (FEA) is one of the numerical methods in science that mostly deal with finding approximate numerical solutions of problems like structural, fluid, thermal or fluid structure interface(FSI). Normally, for thermal and fluid problem, software package like FLUENT and GAMBIT are popular. But latest version of ANSYS includes FLUENT too. 

Hence, without use of software, it is I think almost impossible to work or research in Mechanical Engineering. So, If you are early years of your study in graduation in Mechanical, you need to learn these software as soon as possible because nothing will be of no use, each and every things you do, will work for you some day.

Bevel protractor

What is bevel protractor ? A bevel protractor is a graduated circular protractor with one pivoted arm used for measuring or marking off angles. Sometimes Vernier scales are attached to give more precise readings. It has wide application in architectural and mechanical drawing, although its use is decreasing with the availability of modern drawing software or CAD. Universal bevel protractors are also used by toolmakers, as they measure angles by mechanical contact they are classed as mechanical protractors. The bevel protractor is used to establish and test angles to very close tolerances. It reads to 5 minutes or 1/12° and can measure any angle from 0° to 360°. The bevel protractor consists of a beam, a graduated dial and a blade which is connected to a swivel plate (with Vernier scale) by thumb nut and clamp. When the edges of the beam and blade are parallel, a small mark on the swivel plate coincides with the zero line on the graduated dial. To measure an angle bet

Four laws of thermodynamics

Four laws of thermodynamics The so-called Zeroth Law is a bit more fundamental than the other Three Laws. It came into being after the Three. It essentially says that if each of two systems is in equilibrium with a third system, the first two are in equilibrium with one another.  The First Law basically says that energy or matter can neither be created nor destroyed. In terms of the machine, this meant that the total energy output (work by the machine) is equal to the heat supplied. In other words, the change in the internal energy of a closed system is equal to the heat added to the system minus the work done by the system. Because the system operates in the real world, some energy always escapes into the outside world, thus leading to both inefficiency and the Second Law, which was generated to cover the so-called flaw in the First Law.  The Second Law essentially says that it is impossible to obtain a process where the unique effect is the subtraction of a positive heat

How to proceed software automation ?

Today, large manufacturers are a wonder of automation: not only their manufacturing processes, but their business processes as well. This software-based approach – much of it in the cloud – saves them time and money and increases the transparency of their processes across departments, locations and even partner companies. For small manufacturers, however, the benefits of software-based approaches aren’t so transparent, and many small companies struggle with the best approach to software-based process automation. Software Advice, a Gartner-owned consulting firm that provides research to software buyers, recently pulled data from its interactions with thousands of manufacturing organizations to  uncover trends  in small manufacturing companies (defined as those will annual revenues of $100 million or less) and their aspirations with regard to software purchasing. The goal was to discover these companies’ software needs and their pain points, as well as what would compel them to
