Book Description

This Promotional book, is destintened be part of a Complete Technical Guide entitled: Mechanical Advantages: Ropes, Pulleys, Rigging Systems, and Avoiding Dangerous Resultants (3rd Ed). It has over 500 pages including this book/release is the foundation for the "Pulleys section" of the bigger book, which includes 11 sections: Introduction, Equipment soft goods and hardware, Pulley Systems Explained (this book/release), Safety, Rigging systems, Training, Adventure-recreation, Rescue, Work: trams, cranes, picks, manlifts, and Avoiding dangerous resultants." This book/release is over 150 pages, and 150 pictures, charts, diagrams, and drawings to help communicate, on building a good foundation and understanding of pulleys and their many uses. It includes real life examples of ways pulleys work, how to create various configurations to gain pulley advantage, how to figure out "What the Mechanical Pulley advantage different systems create," Compound, Complex, and Simple pulley systems, effects of mechanical rope grabs on rope, and many more things related to pulleys and the various connectors, ropes, and other gear. This book begins with some advanced basics, and then addresses many skills and situations used by people, rescue professionals, and skilled work professionals interested in pulleys, ropes, and various systems. It is a great book for rescue professionals, SAR, Firefighters, Sailing, EMS Personnel, FEMA Personnel, construction workers, adventure professionals and recreationalists, or anyone who works with ropes, and pulleys. It is explains the difference between simple, complex, and compound pulley systems. How a pulley system may load a component in such a way that it becomes a disadvantage, and may cause an anchor or other component to fail. Within these pages I explain safety, situational awareness, on various ways to rig and use pulley systems, why they work, and how to gain the "Maximum efficiency and simplicity, with a minimum amount of effort and equipment, while maintaining a low risk exposure (Safety Picture). I have included almost 100 pictures and diagrams to help communicate these principles and concepts. With over 40 years of experience teaching, rescuing, working, and fiddling with pulleys and rigging gear, I believe I have some insights not found in any other text on the subject. Thanks for your interest.Douglas S. Hansen

Book Description

Pulley Systems Explained has evolved into a full 300 dpi color book, with more than 280 pages. It includes many more diagrams, drawings, examples, pictures, and applications. It explains the difference between simple, complex pulley systems, and how compounding effect works, how to determine the pulley advantage of any pulley system, ways to use them at work, for rescue, or while on an adventure. Including a special section of applications, strategies, and tactics. A sampling of many situations we run into while working in real life. It teaches skills, and helps prepare you to handle those complex situations we all must deal with, yet there is no simple answer. I share other related things that 40 years of "walking the talk" has brought. ♦"Book knowledge is good information, combine training, and it becomes usable knowledge, add experience and you have the pure gold of knowledge." This is the "Pulley Section" of the "Ropes, Pulleys, Rigging Systems, and Avoiding Dangerous Resultants Book Series. "Pulley Systems Explained" is the evolution of many years of writing, collecting, drawing, taking pictures, working with other professionals, rewriting, organizing, and fine tuning articles and books about Ropes, Pulleys, Rigging System, and Safety (Avoiding Dangerous Resultants). Rope is one of the most common simple machines, add pulleys and we now have a system. This book if full of systems you can use at work, during rescues, and at home, or while on adventures. There are examples, challenges, quizzes, charts, diagrams, and pictures, and more ways we can work with pulleys to make our lives better. "Maximum Efficiency and Simplicity with a Minimum of Effort and Equipment; while maintaining low risk exposure." It defines an approach to assembling our systems. Pulley Systems Explain is also a good companion book to use with ®vRigger Software for learning various pulley rigging systems.

Book Description

In Aristotle's Empiricism, Jean De Groot argues that an important part of Aristotle's natural philosophy has remained largely unexplored and shows that much of Aristotle's analysis of natural movement is influenced by the logic and concepts of mathematical mechanics that emerged from late Pythagorean thought. De Groot draws upon the pseudo-Aristotelian Physical Problems XVI to reconstruct the context of mechanics in Aristotle's time and to trace the development of kinematic thinking from Archytas to the Aristotelian Mechanics. She shows the influence of kinematic thinking on Aristotle's concept of power or potentiality, which she sees as having a physicalistic meaning originating in the problem of movement.De Groot identifies the source of early mechanical knowledge in kinesthetic awareness of mechanical advantage, showing the relation of Aristotle's empiricism to more ancient experience. The book sheds light on the classical Greek understanding of imitation and device, as it questions both the claim that Aristotle's natural philosophy codifies opinions held by convention and the view that the cogency of his scientific ideas depends on metaphysics.

Book Description

Every year workers' low-back, hand, and arm problems lead to time away from jobs and reduce the nation's economic productivity. The connection of these problems to workplace activities-from carrying boxes to lifting patients to pounding computer keyboards-is the subject of major disagreements among workers, employers, advocacy groups, and researchers. Musculoskeletal Disorders and the Workplace examines the scientific basis for connecting musculoskeletal disorders with the workplace, considering people, job tasks, and work environments. A multidisciplinary panel draws conclusions about the likelihood of causal links and the effectiveness of various intervention strategies. The panel also offers recommendations for what actions can be considered on the basis of current information and for closing information gaps. This book presents the latest information on the prevalence, incidence, and costs of musculoskeletal disorders and identifies factors that influence injury reporting. It reviews the broad scope of evidence: epidemiological studies of physical and psychosocial variables, basic biology, biomechanics, and physical and behavioral responses to stress. Given the magnitude of the problem-approximately 1 million people miss some work each year-and the current trends in workplace practices, this volume will be a must for advocates for workplace health, policy makers, employers, employees, medical professionals, engineers, lawyers, and labor officials.

Book Description

A key unresolved issue lies at the heart of our science -- the quest of Aristotle, Newton, Einstein, Hawking and many others, now widely known as the Theory of Everything. This ultimate understanding is expected to transform science and resolve its many mysteries -- all via one single overlooked principle in nature that will explain, simplify and unify everything. This quest has produced theories such as Special Relativity, General Relativity and Quantum Mechanics, enormous investments in powerful particle accelerators and space telescopes, and such recent pursuits as "Dark Matter" and "Dark Energy." But enormous problems remain: these theories, projects and pursuits are all completely separate and frequently incompatible, presenting unresolved abstractions, speculation, paradoxes and mysteries that often even violate our laws of physics, upon closer examination. As a result, the Theory of Everything continues to elude us, with no clear way forward. The Final Theory clearly shows why this is the case, exposing centuries of well-intentioned but misguided scientific thought that has locked us into an erroneous and highly troubled energy-based science that has taken us far off track. It corrects the errors in our scientific legacy, showing that energy is actually a misunderstanding of the unifying principle we have sought for centuries -- a principle that is active all around us, producing all known phenomena such as gravity, light, electricity and magnetism. This new understanding replaces both Newton's "gravitational force" theory and Einstein's "warped space-time" General Relativity Theory, while also overturning such theories as Special Relativity and Quantum Mechanics. In their place is a single simple principle that finally demystifies, explains and unifies everything. Read The Final Theory and judge for yourself whether the Theory of Everything has finally arrived!
