The bicycle is almost unique among human-powered machines in that it uses human muscles in a near-optimum way. This new edition of the bible of bicycle builders and bicyclists provides just about everything you could want to know about the history of bicycles, how human beings propel them, what makes them go faster, and what keeps them from going even faster. The scientific and engineering information is of interest not only to designers and builders of bicycles and other human-powered vehicles but also to competitive cyclists, bicycle commuters, and recreational cyclists.

The third edition begins with a brief history of bicycles and bicycling that demolishes many widespread myths. This edition includes information on recent experiments and achievements in human-powered transportation, including the "ultimate human- powered vehicle," in which a supine rider in a streamlined enclosure steers by looking at a television screen connected to a small camera in the nose, reaching speeds of around 80 miles per hour. It contains completely new chapters on aerodynamics, unusual human-powered machines for use on land and in water and air, human physiology, and the future of bicycling. This edition also provides updated information on rolling drag, transmission of power from rider to wheels, braking, heat management, steering and stability, power and speed, and materials. It contains many new illustrations.

Suspension is probably the most misunderstood aspect of motorcycle performance. This book, by America’s premier suspension specialist, makes the art and science of suspension tuning accessible to professional and backyard motorcycle mechanics alike. Based on Paul Thede’s wildly popular Race Tech Suspension Seminars, this step-by-step guide shows anyone how to make their bike, or their kid’s, handle like a pro’s.

Thede gives a clear account of the three forces of suspension that you must understand to make accurate assessments of your suspension’s condition. He outlines testing procedures that will help you gauge how well you’re improving your suspension, along with your riding. And, if you’re inclined to perfect your bike’s handling, he even explains the black art of chassis geometry. Finally, step-by-step photos of suspension disassembly and assembly help you rebuild your forks and shocks for optimum performance.

The book even provides detailed troubleshooting guides for dirt, street, and supermoto--promising a solution to virtually any handling problem.

Satellite Basics for Everyone [EPUB]

Satellite Basics for Everyone [EPUB]
Satellite Basics for Everyone: An Illustrated Guide to Satellites for Non-Technical and Technical People by C Robert Welti
2012 | EPUB | 3.68MB

Learn about satellites that affect us every day, how they work, and how we can place and keep them on orbit.

Satellite Basics for Everyone presents an introduction and overview to satellites. It’s written as clearly and understandably as possible for a wide audience. It provides a learning tool for grade school students. High school and college students can use it for helping them decide on career fields. It’s for people with curious minds who want to know about satellites that affect their daily lives. And, it provides a training tool and an overview for people who build, operate, and use data collected by satellites.

Satellite Basics for Everyone describes satellite missions, orbits, population, closeness, debris, collision risk, builders, owners, operators, launch vehicles, and costs. Focus then turns to describing the orbit, components, environment, and operation of the geostationary communications satellite because it affects our daily lives the most by providing television, radio, commercial business, Internet and telephone services. A description of satellite motion prepares for the included Mission Planning Example of how to place and keep this satellite on orbit and keep the antennas pointing in the right direction to perform its mission.

The main objective of this book is to stimulate a broad interest in engineering and science.
