Last Day: Four Engineering Books Free on Kindle Until Midnight PT

This is the last day. All four of my engineering books are free on Kindle only until midnight Pacific time, and after that they go back to their normal price. If you meant to pick one up this week, now is the moment.

The four books

GD&T Professional Exam Guide. For anyone preparing for the ASME GDTP certification, written to the 2018 edition of Y14.5. It has 21 chapters, an original drawing for every concept, 12 exam-style questions per chapter and two full practice exams. Earlier this week I wrote about what the 2018 exam tests that 2009-era books miss.

Practical Airframe Stress Analysis, Volume 1. Metallic structure from margins and the Part 25 factors through beams, buckling, joints, fittings and lugs, with 85 worked examples taken to a margin. The post on a margin of safety worked like a checker would want it shows the style.

Practical Airframe Stress Analysis, Volume 2: Composite Structure. Laminates, failure criteria, allowables, bolted and bonded joints, impact damage and repairs, with 78 worked examples. See three mistakes composite analysts make.

Python for Aerospace Stress Engineers. From first scripts to tested tools for load cases, section properties and checks, with code, data and notebooks for readers. The post on replacing a margins spreadsheet with tested Python gives the flavour.

Before the clock runs out

You do not need a Kindle device: the free Kindle app opens these on a phone, a tablet or a computer. Each one stays in your library once downloaded, so you can grab all four now and read them when a project calls for it. The buttons below go to your own country’s Amazon store, and nothing is asked of you in return.

Which one to start with

If you have an exam coming, start with the GD&T guide and its practice exams. If you are new to a stress office, Volume 1 is the foundation and Volume 2 builds on it for composite work. If you already know the methods but spend your evenings fixing spreadsheets, the Python book will pay back its reading time on the first project. And if you are not sure, take all four today: they cost nothing until midnight Pacific, and you can decide later which one earns a place on your desk.

Why I did this

I wrote these books from twenty years of work in aerospace and energy structures, for the engineers I wish I had had beside me when I started. Five free days is the simplest way I know to put them in front of the people who need them. Thank you to everyone who downloaded one this week, and to everyone who wrote to tell me which chapter helped. That feedback shapes the next edition, so if something in a book was unclear or wrong, reply to any of my emails or use the contact page and I will read it.

All four, free until midnight Pacific
