Question

Roarks equations worksheets

New to PTC community but long time user of mathcad.

 

I need to get the Roarks formula's for stress and strain ebook but as best I can tell from the forums it is no longer provided with mathcad AND it's not available on the forums for download (or on the web as best I can tell).  Is this correct?

 

TIA

I thought the Mathcad Roarks libraries and other engineering ebooks were now distributed by knovel.com?

That's what I'm trying to figure out.  Where can you download/purchase the ebooks.  I searched on there and couldn't find it but maybe I searching wrong?

Sorry, "Roark's Formulas for Stress and Strain" is not available on Knovel.

Above is what I got searching Knovel.com but it recommends alternative books.

 

I had the original Mathcad Roark's handbook.  Also had the hardcopy book.

Emailed the book publishers about converting all the files to Prime and reestablishing all the hyperlinks.

They were simply not interested.

Converting to Prime from Mathcad all files can be done in one session with the converter.

I am only a little way through in re-establishing the links [control]+mouse click in the now Prime worksheets.

Just too busy.

 

Cheers

Terry

Article (2024) - "Links to Roark's Worksheet Library - 6th Edition available in Mathcad Prime format for purchase in PTC Webstore seem broken, or content has been removed": https://www.ptc.com/en/support/article/CS369696

I had started to convert Roarks Formula's to Prime some time ago but got bogged down with work. As I recall, I think I was into Chapter 7 when I stopped. I have since retired and was thinking of completing the effort. I can make it available to the Mathcad community when completed if there is interest, but it will take me some time to complete.
