WHAT IS MECHANICAL ENGINEERING?

Technically,mechanical engineering is the application of the principles and problem solving techniques of engineering from design to  manufacturing to the market place for any object

Mechanical engineers analyze their work using the principles of motion,energy and force -ensuring that designs function safely,efficiently and reliably all at a competitive cost

Most Important Software for Mechanical Engineers

There are many software packages used by mechanical engineers, but there are a few that are used consistently throughout industry. The level of proficiency that is required with specific software packages is dependent on your role as an engineer. However, every mechanical engineer should have at least a basic familiarity with most of the software on this list. 

Math cad is computer software primarily intended for the verification, validation, documentation and re-use of engineering calculations.^[3] First introduced in 1986 on DOS, it was the first to introduce live editing of typeset mathematical notation, combined with its automatic computer

Math cad is possibly the one piece of software that is useful to every mechanical engineer, regardless of job function. Math cad gives you the ability to do math within a document, as well as to add relevant images and text to explain your work. You can add plots which either read from arrays of data, or which can be linked to defined equations. The result is a beautifully formatted document containing your "hand" calculations.

• Ability to write and evaluate equations
• Unit conversion
• Plotting
• Linear algebra -- useful for solving 3D statics problems, for solving systems of linear equations, etc.
• Symbolic equation solver -- useful for when you just don't feel like manually solving for the integral of some complex equation

Programming -- useful for numeric analysis

Current releases

As of August 2018, there are two actively maintained Math cad releases and a free express version available to consumers:

• Math cad 15.0 was originally released in June, 2010. Its first maintenance release was released in November, 2010. Math cad 15.0 is the next progressive release of the traditional product line, sharing the same worksheet file structure and extension as its predecessor, Math cad 14.0.
• Math cad Prime 6.0.0.0, P T C’s latest generation product, was introduced in October 2019. This is P T C's latest release.
• PTC Math cad Express Free-for-Life Engineering Calculations Software - a Math cad Prime 30-day trial, but when the 30-day trial period has ended, it is possible to continue using PT C Math cad Express for an unlimited time. This  Freemium pilot marks a new marketing approach for PT C. Review and markup of engineering notes can now be done directly by team members without them all requiring a full Math cad Prime license

  Computer Aided Design (CAD) Software

  Auto CAD is a commercial computer-aided design (CAD) and drafting software application. Developed and marketed by Auto desk,^[1] Auto CAD was first released in December 1982 as a desktop app running on microcomputers with internal graphics controllers.^[2] Before Auto CAD was introduced, most commercial CAD programs ran on mainframe computers or minicomputers, with each CAD operator (user) working at a separate graphics terminal.^[3] Since 2010, Auto CAD was released as a mobile- and web app as well, marketed as Auto CAD 360.

  Auto CAD is used in industry, by architects, project managers, engineers, graphic designers, city planners and other professionals. It was supported by 750 training centers worldwide in 1994.^[1]

  
  

  A 3D CAD (Computer Aided Design) package is especially useful to any engineer with a focus on design. This software allows you to build 3D models of parts and assemblies. For instance, you could model all of the individual parts of an engine, and then combine them into an assembly. This will allow you to ensure that all of the parts fit together as intended. Many CAD packages allow you to do things like allow motion of parts (i.e. to allow a shaft to rotate) and to check for inter ferences between parts. Most CAD packages have a drafting component that allows you to create 2D drawings of your parts so that they can be manufactured. Many CAD tools also have direct integration into an FEA(Finite Element Analysis) package so you can iterate seamlessly between design and analysis. Popular examples of 3D CAD software include Solid Works, Uni graphics NX, CATIA, and Auto desk Inventor.

  

  
  

  Auto CAD is a software package created for Windows and usually, any new Auto CAD version supports the current Windows version and some older ones. Auto CAD 2016 to 2020 support Windows 7 up to Windows 10.^[25]

  Mac

  Auto desk stopped supporting Apple's Macintosh computers in 1994. Over the next several years, no compatible versions for the Mac were released. In 2010 Autodesk announced that it would once again support Apple's Mac OS X software in the future.^[26] Most of the features found in the 2012 Windows version can be found in the 2012 Mac version. The main difference is the user interface and layout of the program. The interface is designed so that users who are already familiar with Apple's macOS software will find it similar to other Mac applications.^[19] Auto desk has also built-in various features in order to take full advantage of Apple's Track pad capabilities as well as the full-screen mode in Apple's OS X Lion.^[18][19] Auto CAD 2012 for Mac supports both the editing and saving of files in drawing formatting that will allow the file to be compatible with other platforms besides the OS X.^[18] Auto CAD 2019 for Mac requires Apple OS X v10.11 (El Capitan) or later.

  Auto CAD LT 2013 was available through the Mac App Store for $899.99. The full-featured version of Auto CAD 2013 for Mac, however, wasn't available through the Mac App Store due to the price limit of $999 set by Apple. Auto CAD 2014 for Mac was available for purchase from Auto desk's Web site for $4,195 and Auto CAD LT 2014 for Mac for $1,200, or from an Auto desk Authorized Reseller.^[26] The latest version available for Mac is Auto CAD 2019 as of December 2018. As of 2019, no Auto CAD release is listed for purchase on the Mac App Store.

  Finite Element Analysis (FEA) Software

• Finite Element Analysis (FEA) is useful to any engineer that needs to perform structural analysis. This software allows you to analyze stresses and deflections in complex structures. Popular examples include ANSYS and Nastran. Typically a structure will be modeled in a 3D CAD program and then ported over to the FEA software. Previously, the porting process involved exporting the CAD model to a file format that could then be interpreted by the FEA software, but now many FEA packages integrate directly with CAD packages to make the transition seamless. Once the geometry is built, a mesh is created to discretize the structure into elements. Forces and constraints are applied, and the model can then be solved. From the solved model you can interrogate stresses and deflections in the structure

 ADVANTAGES AND DISADVANTAGES OF FEM

ADVANTAGES

• model irregular shaped bodies quiet easily
• handle general load conditions without difficulty
• handle unlimited numbers and kinds of boundary conditions

                                                       DISADVANTAGES

• The finite element method is a time consuming process i.e .,it requires longer time for solving
