If you feel you’ve lost your bearings, you aren’t alone! Global pandemic . . . Economic crisis . . . Racial tensions . . . Political polarization . . . Climate change. The converging crises expose our timeless need for an internal compass to guide us through disruption, disorientation and change. James Harnish invites you into six crucial moments when Jesus found his bearings by recalling words and stories from the Old Testament. By connecting Jesus’ story with your own, you can find your bearings as you walk the way Jesus walked in the way that Jesus walked it. It’s the way that leads to life! Questions for Reflection create an opportunity for you to pause, find your place in the story, and determine your next step along the way. These may also be used for journaling or small group discussion.

Never be lost again! This concise and handy guide will help you get your bearings and find your way out of the wilderness no matter your equipment. Finding your campsite, a spectacular view, or your way home can be difficult, especially when your phone or GPS malfunctions. But knowing how to use a magnetized compass, paper map, and the positions of the sun, moon, stars, and other practical aids in pathfinding will help outdoorsman find their way in almost any kind of terrain. Navigating With or Without a Compass will teach you the basics of using that essential tool, such as the difference between true north and magnetic north based on where you are and using compass bearings from a map and in the field to determine location. However if you find yourself without a compass, this handy guide will also give you natural signs and guideposts for pathfinding, such as the way the wind blows, trees grow, or flowers bloom. Also covered will be determining direction through reading the Sun and the shadows it forms, the position and stages of the Moon, and familiarizing oneself with the principal constellations to guide you and determine the time at night. Perfect for the skilled woodsman or just a walk in the woods, Navigating With or Without a Compass is filled with tips and essential knowledge indispensible for hikers, campers, scouts and nature lovers.
Bearings: from Technoloogical Foundations to Practical Design Applications provides a modern study of bearing types, design factors, and industrial examples. The major classes of bearings are described, and design concepts are covered for rolling elements, surfaces, pivots, flexures, and compliance surfaces. Fluid film lubrication is presented, and the basics of tribology for bearings is explained. The book also looks at specific applications of bearing technology, including bearings in vehicles, rotating machinery, machine tools, and home appliances. Case studies are also included.
Compiling the expertise of nine pioneers of the field, Magnetic Bearings - Theory, Design, and Application to Rotating Machinery offers an encyclopedic study of this rapidly emerging field with a balanced blend of commercial and academic perspectives. Every element of the technology is examined in detail, beginning at the component level and proceeding through a thorough exposition of the design and performance of these systems. The book is organized in a logical fashion, starting with an overview of the technology and a survey of the range of applications. A background chapter then explains the central concepts of active magnetic bearings while avoiding a morass of technical details. From here, the reader continues to a meticulous, state-of-the-art exposition of the component technologies and the manner in which they are assembled to form the AMB/rotor system. These system models and performance objectives are then tied together through extensive discussions of control methods for both rigid and flexible rotors, including consideration of the problem of system dynamics identification. Supporting this, the issues of system reliability and fault management are discussed from several useful and complementary perspectives. At the end of the book, numerous special concepts and systems, including micro-scale bearings, self-bearing motors, and self-sensing bearings, are put forth as promising directions for new research and development. Newcomers to the field will find the material highly accessible while veteran practitioners will be impressed by the level of technical detail that emerges from a combination of sophisticated analysis and insights gleaned from many collective years of practical experience. An exhaustive, self-contained text on active magnetic bearing technology, this book should be a core reference for anyone seeking to understand or develop systems using magnetic bearings.
This handbook shows how to prevent bearing failure, how to avoid replacement and down-time costs, and how to solve bearing failure problems quickly when they do occur - avoiding delayed orders and lost business. No other handbook covers such a wide range of bearing types and seals, shafts and housing, materials and manufacture. There is no other troubleshooting guide to help technicians and mechanics monitor, mount and dismount, and lubricate correctly. Rolling Bearings Handbook and Troubleshooting Guide puts the right maintenance and diagnostic procedures at your fingertips.
Covering the fundamental principles of bearing selection, design, and tribology, this book discusses basic physical principles of bearing selection, lubrication, design computations, advanced bearings materials, arrangement, housing, and seals, as well as recent developments in bearings for high-speed aircraft engines. The author explores unique solutions to challenging design problems and presents rare case studies, such as hydrodynamic and rolling-element bearings in series and adjustable hydrostatic pads for large bearings. He focuses on the design considerations and calculations specific to hydrodynamic journal bearings, hydrostatic bearings, and rolling element bearings.
