# !!> Reading ➵ How Round Is Your Circle?: Where Engineering and Mathematics Meet ➭ Author Chris Sangwin – Tactical-player.co.uk

How Do You Draw A Straight Line How Do You Determine If A Circle Is Really Round These May Sound Like Simple Or Even Trivial Mathematical Problems, But To An Engineer The Answers Can Mean The Difference Between Success And Failure How Round Is Your Circle Invites Readers To Explore Many Of The Same Fundamental Questions That Working Engineers Deal With Every Day It S Challenging, Hands On, And Fun John Bryant And Chris Sangwin Illustrate How Physical Models Are Created From Abstract Mathematical Ones Using Elementary Geometry And Trigonometry, They Guide Readers Through Paper And Pencil Reconstructions Of Mathematical Problems And Show Them How To Construct Actual Physical Models Themselves Directions Included It S An Effective And Entertaining Way To Explain How Applied Mathematics And Engineering Work Together To Solve Problems, Everything From Keeping A Piston Aligned In Its Cylinder To Ensuring That Automotive Driveshafts Rotate Smoothly Intriguingly, Checking The Roundness Of A Manufactured Object Is Trickier Than One Might Think When Does The Width Of A Saw Blade Affect An Engineer S Calculations Or, For That Matter, The Width Of A Physical Line When Does A Measurement Need To Be Exact And When Will An Approximation Suffice Bryant And Sangwin Tackle Questions Like These And Enliven Their Discussions With Many Fascinating Highlights From Engineering History Generously Illustrated, How Round Is Your Circle Reveals Some Of The Hidden Complexities In Everyday Things

As an engineer, a lot of mathematics has been a bit of a mystery to me As this book explains, in engineering there are no irrational numbers because engineers work in approximations That is one of the biggest differences between engineering and mathematics, but the book also gives a big insight into some of the mathematical roots of engineering tools and techniques.The chapter on planimeters was a bit hard going for me, but that s because I ne

This book does what it claims and bridges the boundry between Mathematics and Enginering It has some insights into how various linkages work, why rollers don t need to be round, how to make a ruler, how to draw a straight line and of course how round is your circle The book looks at historical attempts to solve these problems and the various inventions that were produced along the way Slide rules are explained in depth and if you ve an old set of cal

Good Quality, Would repeat

Being a mechanical engineer myself, I m fascinated about geometry and its application on kinematics of mechanisms, which is what this book is specialized at The examples are amazing and the book is a good option of entertainment, specially if you re after something different.

Recommended to me on yahoo groups.A fantastically interesting book if you are interested in Engineering and Mathematics.Euclid is now my new hero
