Case Study: Alaska Airlines Flight 261

A jackscrew (or screw jack) is a type of jack you will have probably seen stowed in your car but they are used extensively in other mechanical devices. They operate by turning a leadscrew to produce linear motion of a ‘load-nut’. An acme thread form is most commonly used, as this t...

Excel 2010 A Return to Excellence

Helping You Make and Share Calculations with MS Excel

Use our XLC add-in for Excel to display cell formula as easily readable mathematical equations. Now that cell formulae can be checked directly against mathematical expressions you'll never insert an incorrect cell formula again! Because it works in the familiar Excel environment it is easy to learn and can be universally read (even if the XLC add-in is not installed). Downloading calculations from the ExcelCalcs Repository gives users a head start in solving their technical problems. Members rate and comment on their Repository downloads to provide useful feedback for other users. They can even use the calculation’s ‘Forum Link’ to ask a question of the author. The site forum is open and honest and members receive a quick response to any query raised. The site administrators are always happy to help you whether you have a question about the site or relating to Excel generally. Video material in our ExcelCalcs TV section of the website provides extensive XLC tutorials.

Eng-Tips Forum Five Star tip. "an addin that displays excel formulas symbolically for easy checking and for presentation. Displaying formulas is a real kick!" Read all the comments.

Institute of Mechanical Engineers Forum - "I've had a play with it and it's great, it's driven me nuts for years having to do all my equations in equation editor and then update them when things change". Super Forum Member

User Testimonials "The best thing about XLC is that equations are a really great check on the cell formula. It's easy to make a mistake with Excel formulas (as I know because I make them all the time) but its easy to see where you have gone wrong when you check against equations." Debbie_Williams.

"I have only been using it for a week or so but XLC is an answer to my prayers. I had been using the MS equation editor which took hours of my time and I often mistyped. Now I can generate equations directly from cell formulas instantaneously. Great idea. Thanks again and well done." Helen_Miller.

"I think I will be ditching MathCAD and using this instead. Then I can send my calculations to anyone, we all have Excel whereas only a few of us have MathCAD." Boffin.

"There are loads of useful web calculations on the internet but the ExcelCalcs Repository gives it to me in an Excel format so I can easily copy and integrate them into my own calculations. This afternoon you saved me hours by downloading a repository calculation rather than authoring my own - and all this for free - thank you!" Mark_Rawlings.

"What a great plug-in (and the price is right, too!) I have been looking for something like this for years. Highly recommended!" jhardy.
