10 Sites That Every Engineer Should Know About

Here’s another post inspired by an office discussion. We were discussing our favourite engineering based websites and realised the results would make a great blog post. So after a rummage through our bookmarks and a little further debate we’ve come up with our top ten sites. We tried to keep the list balanced so you’ll find a few resource sites, a little bit of fun and one or two sites that aren’t purely engineering sites, but contain valuable knowledge for engineers. Do you have a favourite site that we haven’t included? Why not add a comment below and give your favourites a plug.


A wealth of engineering related news, videos, resources and jobs.


2. Engineering Formulas

A website packed full of formula for Fluid Mechanics, Failure Criteria, Finance and loads of things that don’t begin with F too. A great site for lovers of Greek letters and other squiggles. Other parts of the site have information on materials, units, design and maths.

Visit…  eFunda: Engineering Formulas

3. The Engineering Toolbox

A great site, well structured into various engineering categories that lets you drill down to find the information you need. The flow of the site is a little spoiled by too many Google Ads links, but that is just a minor irritation.

Visit…  The Engineering Toolbox

4. LinkedIn

Not strictly an engineering resource, but LinkedIn is a great place to network with fellow engineers (it’s a bit like Facebook for grown-ups) and has some really useful special interest groups for sharing knowledge, meeting like-minded professionals and exchanging job opportunities.

5. GlobalSpec

Calling itself “The Engineering Search Engine”, GlobalSpec is packed full of engineering products and suppliers. Has some great email newsletters and product alert emails. You can even find Prosig on GlobalSpec.

6. How Stuff Works

Whenever we need bit of extra background information for an office discussion this website is one of our first ports of call. Packed full of straightforward explanations

7. Eng-Tips Forums

A fine collection of discussion forums, blogs, whitepapers and more. Covers a wide range of engineering fields.

8. Wikipedia

Again, not strictly an engineering site, but Wikipedia can’t be ignored when seeking information. Much has been made of the possible innaccuracies of Wikipedia’s articles, but genarally the scientific and engineering pages are well maintained.

9. Discover Engineering

A fantastic site for students or anyone new to engineering. Or just about anyone who enjoys quirky science projects and engineering themed games and activities. We all need a little light relief, right?

Visit…   Discover Engineering

10. Fun-Engineering

Another bit of fun to finish with. Fun-Engineering (maintained by Prof. Jim McGovern of the Department of Mechanical Engineering at the Dublin Institute of Technology) is a great little site, full of engineering gems. To my mind it is sites like this that make the WWW what it is.

Chris Mason

General Manager at Prosig
Chris fell in love with technology and innovation in the early days of personal computing (Sinclair ZX80's, Commodore PETs & Apple ]['s) This hobby became a career in software development, product development, team leadership, web development, and marketing. He is now General Manager at Prosig & DJB Instruments, both part of Condition Monitoring Technology Group. In 2019 Chris completed an Executive MBA at the University of Winchester where he focused on innovation and strategy.

    Chris, these are indeed good sites but I would also like to draw your attention to our Science & Engineering Encyclopedia site at which has over 5000 pages of information covering many subjects. With free online calculations and conversions, and hundreds of NVH topics some of which have live plotting capabilities we feel it deserves a look from yourselves.
    Regards, Charlie.

  2. Chris Mason

    Hi Charlie,
    Thanks for the link. Indeed, a very nice site and well worthy of inclusion in our list. Maybe, if we get some more suggestions or take another look at our shortlist, we will do a Mark II post and include diracdelta.
    Many Thanks, Chris

  3. Chris Mason

    Hi Zach

    Thanks for the links. A really great site and nice design too!! I have already started a list so I don’t think it should be too long before we publish “10 More Sites That Every Engineer Should Know About”.

  4. Chris Mason

    Thanks Michael. I’ve added that to our growing list of sites for the followup post.

  5. John Hayes

    Hey Chris,
    Thanks for noting on your list. We’re working hard to make it a great destination, and I can’t tell you how nice it is to be recognized for that effort.

  6. Chris Mason

    No problem, John. is a great site. Of course, feel free to add as many links as you like to the Noise & Vibration Measurement Blog. 🙂

  7. Rahul Bhowmick

    I’m surprised that Wolfram Alpha didn’t make the list. This is something I have seen every (almost) Science & Engineering student use. Especially considering how Apple recently integrated Siri with Wolfram Alpha on their Iphone 4S.

  8. Chris Mason

    Hi Rahul. You are quite correct, Wolfram Alpha has certainly gone from strength to strength. I think it will be a definite candidate when we update the list. There are so many great sites, perhaps next time we should do a Top 20!

    1. Chris Mason

      Thanks for the suggestion, Keith. We do still intend to write a follow-up post one day with some of the great suggestions we’ve received here. Engineers Edge certainly seems like a very useful site.

    Hai Mr. Chris Mason, good information a true engineer will love to keep this as his bible.

    Hi Chris,
    This is a great list, there are lots of useful sites here. One other that you may be interested to check out is MechaniCalc ( This site has calculators and reference material for mechanical engineers, and it is much more clean and intuitive than many of the other similar sites such as Engineer’s Edge.

  11. Kevin

    Engineers Edge ( is the most comprehensive website out there. They are claiming more than 150,000 webpages – most is for mechanical engineering and designers. Use the search function to find stuff.

  12. Formwork Engineer

    Check out Optimal Beam (, it is a structural beam calculator (free option)

    You can specify unlimited support types and loading conditions on your beam model. It gives you support reactions, shear force, bending moment, deflection, and stress diagrams. Its the only site that analyzes indeterminate beams in the free version. Useful for civil and mechanical engineers and students.

    Good list however for design and engineering reference information I always use Engineers Edge ( then engineering Toolbox.
