With new chapters, homework problems, case studies, figures, and examples, Ballistics: Theory and Design of Guns and Ammunition, Third Edition encourages superior design and innovative applications in the field of ballistics. It examines the analytical and computational tools for predicting a weapon\'s behavior in terms of pressure, stress, and velocity, demonstrating their applications in ammunition and weapons design. New coverage in the Third Edition includes gas-powered guns, and naval ordinance. With its thorough coverage of interior, exterior and terminal ballistics, this new edition continues to be the standard resource for those studying the technology of guns and ammunition. This bestselling DIY handbook now features new and expanded projects, enabling ordinary folks to construct 16 awesome ballistic devices in their garage or basement workshops using inexpensive household or hardware store materials and this step-by-step guide. Clear instructions, diagrams, and photographs show how to build projects ranging from the simple match-powered rocket to the more complex tabletop catapult and the offbeat Cincinnati fire kite. The classic potato cannon has a new evil twin—the piezo-electric spud gun and the electromagnetic pipe gun has joined the company of such favorites as the tennis ball mortar. With a strong emphasis on safety, the book also gives tips on troubleshooting, explains the physics behind the projects, and profiles scientists and extraordinary experimenters such as Alfred Nobel, Robert Goddard, and Isaac Newton. This book will be indispensable for the legions of backyard toy-rocket launchers and fireworks fanatics who wish every day was the fourth of July.
