Flexure hinges hold several advantages over classical rotation joints, including no friction losses, no need for lubrication, no hysteresis, compactness, capacity to be utilized in small-scale applications, ease of fabrication, virtually no assembly, and no required maintenance. Compliant Mechanisms: Design of Flexure Hinges provides practical answers to the present and future needs of efficient design, analysis, and optimization of devices that incorporate flexure hinges. With a highly original approach the text: Discusses new and classical types of flexure hinges (single-, two- and multiple-axis) for two- and three-dimensional applications Addresses a wide range of industrial applications, including micro- and nano-scale mechanisms Quantifies flexibility, precision of rotation, sensitivity to parasitic loading, energy consumption, and stress limitations through closed-form compliance equations Offers a unitary presentation of individual flexure hinges as fully-compliant members by means of closed-form compliance (spring rates) equations Fully defines the lumped-parameter compliance, inertia and damping properties of flexure hinges Develops a finite element approach to compliant mechanisms by giving the elemental formulation of new flexure hinge line elements Incorporates more advanced topics dedicated to flexure hinges including large deformations, buckling, torsion, composite flexures, shape optimization and thermal effects Compliant Mechanisms: Design of Flexure Hinges provides practical answers and directions to the needs of efficiently designing, analyzing, and optimizing devices that include flexure hinges. It contains ready-to-use plots and simple equations describing several flexure types for the professional that needs quick solutions to current applications. The book also provides self-contained, easy-to-apply mathematical tools that provide sufficient guidance for real-time problem solving of further applications.

With a rigorous and comprehensive coverage, the second edition of Compliant Mechanisms: Design of Flexure Hinges provides practical answers to the design and analysis of devices that incorporate flexible hinges. Complex-shaped flexible-hinge mechanisms are generated from basic elastic segments by means of a bottom-up compliance (flexibility) approach. The same compliance method and the classical finite element analysis are utilized to study the quasi-static and dynamic performances of these compliant mechanisms. This book offers easy-to-use mathematical tools to investigate a wealth of flexible-hinge configurations and two- or three-dimensional compliant mechanism applications. FEATURES - - Introduces a bottom-up compliance-based approach to characterize the flexibility of new and existing flexible hinges of straight- and curvilinear-axis configurations - - - Develops a consistent linear lumped-parameter compliance model to thoroughly describe the quasi-static and dynamic behavior of planar/spatial, serial/parallel flexible-hinge mechanisms - - - Utilizes the finite element method to analyze the quasi-statics and dynamics of compliant mechanisms by means of straight- and curvilinear-axis flexible-hinge elements - - - Covers miscellaneous topics such as stress concentration, yielding and related maximum load, precision of rotation of straight- and circular-axis flexible hinges, temperature effects on compliances, layered flexible hinges and piezoelectric actuation/sensing - - - Offers multiple solved examples of flexible hinges and flexible-hinge mechanisms. - This book should serve as a reference to students, researchers, academics and anyone interested to investigate precision flexible-hinge mechanisms by linear model-based methods in various areas of mechanical, aerospace or biomedical engineering, as well as in robotics and micro-/nanosystems.

Trust Responsibly - Jakob Ohlhorst - Bog - Taylor & Francis Ltd - Plusbog.dk

Trust Responsibly - Jakob Ohlhorst - Bog - Taylor & Francis Ltd - Plusbog.dk

This book offers a defence of Wrightean epistemic entitlement, one of the most prominent approaches to hinge epistemology. It also systematically explores the connections between virtue epistemology and hinge epistemology. According to hinge epistemology, any human belief set is built within and upon a framework of pre-evidential propositions – hinges – that cannot be justified. Epistemic entitlement argues that we are entitled to trust our hinges. But there remains a problem. Entitlement is inherently unconstrained and arbitrary: We can be entitled to any hinge proposition under the right circumstances. In this book, the author argues that we need a non-arbitrariness clause that protects entitlement from defeat. This clause, he argues, is to require epistemic virtue. Virtuous cognitive dispositions provide the non-arbitrariness clause that protects entitlement from defeat. The epistemic character of the agent who holds a particular set of hinges tells us something about the hinges’ epistemic status. Conversely, epistemic virtues are cognitive dispositions and capacities that rely on hinge propositions – without trusting in some hinges, we would be unable to exercise our virtues. Trust Responsibly will appeal to scholars and advanced students working on epistemology, Wittgenstein, and virtues.

Meet Your Body - Noah Karrasch - Bog - Jessica Kingsley Publishers - Plusbog.dk

Many of us hold on to old fears, traumas and stresses and allow them to define and frame our lives. This book shows how to relieve these problems and help you look and feel better on a profound level. Based on the idea that the body is composed of twenty-one important hinges, Meet Your Body shows how we can ''oil'' and free these hinges, stretching the body out so we can feel healthy and happy more of the time.Noah''s therapeutic work uses a hands-on manipulation of the body''s connective tissue designed to enhance posture and freedom of movement. From this theory of structural integration, Karrasch has developed a focus on the inseparable connection between our minds and our bodies, our bodymindcore. Guiding the reader through the various hinges of the body, from the big toe to the hip to the head, the author shows how learning to isolate and stretch these hinges in new ways can lead to a happy bodymindcore, making a great difference to overall health and wellbeing. Each chapter addresses a particular hinge physically as well as sharing ideas about its emotional component, and includes photographs and drawings illustrating a variety of bodymindcore techniques. This book offers people with both ordinary and extraordinary body challenges new ideas for how they can make changes in the way their bodies work for them. A practical guide to releasing bodymindcore trauma, Meet Your Body challenges us all to get in touch with and listen to our bodies to improve our health and overall happiness.
