  • Flight controls have advanced considerably throughout the years. In the earliest biplanes flown by the pioneers flight control was achieved by warping wings and control surfaces by means of wires attached to the flying controls in the cockpit. Figure 1.1 clearly shows the multiplicity of rigging and control wires on an early monoplane. Such a means of exercising control was clearly rudimentary and usually barely adequate for the task in hand.

  • The Department of Energy Fundamentals Handbook entitled Mechanical Science was prepared as an information resource for personnel who are responsible for the operation of the Department's nuclear facilities. Almost all processes that take place in the nuclear facilities involve the use of mechanical equipment and components. A basic understanding of mechanical science is necessary for DOE nuclear facility operators, maintenance personnel, and the technical staff to safely operate and maintain the facility and facility support systems.

  • Since the foundation and up to the current state-of-the-art in control engineering, the problems of PID control steadily attract great attention of numerous researchers and remain inexhaustible source of new ideas for process of control system design and industrial applications. PID control effectiveness is usually caused by the nature of dynamical processes, conditioned that the majority of the industrial dynamical processes are well described by simple dynamic model of the first or second order....

  • This book is meant to be interesting, helpful, and educational to hobbyists, students, educators, and midlevel engineers studying or designing mobile robots that do real work. It is primarily focused on mechanisms and devices that relate to vehicles that move around by themselves and actually do things autonomously, i.e. a robot. Making a vehicle that can autonomously drive around, both indoors and out, seems, at first, like a simple thing.

  • When compared to the constant lubrication problems associated with chain drives, or the mechanical problems and high costs associated with gear drives, belts are the most cost-effective, reliable means of power transmission. However, optimum belt drive performance requires proper maintenance. The potential for long service life is built into every Gates belt. When coupled with a regularly scheduled maintenance program, belt drives will run relatively trouble-free for a long time.

  • In the late twentieth century international trade moved from a political multi-polar system based on the nation-state to a system featuring unified regional trading regimes. An inevitable feature of increased cooperation through bilateral, regional and international arrangements is the emergence of disputes over the interpretation and implementation of the agreed upon commitments. Accordingly, reliable mechanisms for the settlement of trade related disputes have become necessary to ensure the effective and continued functioning of these arrangements.

  • This book is intended primarily to be used as a te xtbook, written on the level of senior and graduate students with proficiency in engineering or sciences. It is intended to bring everyone who wants to solve problems in friction and wear to the same understanding of what is (and, more important, what is not) involved. Most engineers and scientists have learned a few simple truths about friction and wear, few of which seem relevant when problems arise. It turns out that the “truths” are often too simple and couched too much in the terms of the academic discipline in...

  • The discovery and utilization of fire, a simple energy source with many profound uses, was a turning point in the technological evolution of humankind.[26] The exact date of its discovery is not known; evidence of burnt animal bones at the Cradle of Humankind suggests that the domestication of fire occurred before 1,000,000 BC;[27] scholarly consensus indicates that Homo erectus had controlled fire by between 500,000 BC and 400,000 BC.

  • The mechanical behavior of materials describes the response of materials to mechanical loads or deformation. The response can be understood in terms of the basic effects of mechanical loads on defects or atomic motion. A simple understanding of atomic and defect structure is, therefore, an essential prerequisite to the development of a fundamental understanding of the mechanical behavior of materials.
