Springs have been used for more than 500 years as a simple machine that can make other machines work. When you open a screen door, open an umbrella, sit on a sofa, or sleep on a mattress you are using springs. This book explains what springs are and how they help you do everyday things. Topics include: Why won't a Slinky go up stairs? How can a catapult help a place take off? How does a clock work?

Machine Drawing is divided into three parts. Part I deals with the basic principles of technical drawing, dimensioning, limits, fits and tolerances. Part II provides details of how to draw and put machine components together for an assembly drawing. Part III contains problems on assembly drawings taken from the diverse fields of mechanical, production, automobile and marine engineering.

Examines simple machines, ranging from pliers to cranes, in a book with twenty easy-to-do experiments.

Mechanical comprehension tests are used widely during technical selection tests within the careers sector. Mechanical comprehension and reasoning tests combine many different elements. The test itself is usually formed of various pictures and diagrams that illustrate different mechanical concepts and principles. Mechanical comprehension and reasoning tests are normally highly predictive of performance in manufacturing, technical and production jobs. This comprehensive guide will provide you with sample test questions and answers to help you prepare for your mechanical comprehension test. An explanation of the tests and what they involve; Sample timed-tests to assist you during your preparation; Advice on how to tackle the tests; Understanding mechanical advantage; Answers and explanations to the questions; An introduction chapter for fault diagnosis.

For use in schools and libraries only. Includes an assortment of activities using such simple machines as pulleys and levers.

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.

Get Your Move On!
