Introduction and some Ergonomics,e observations relevant to a current need. Examples of each are the transistor, the electric light bulb, the Bessemer converter and the Mannesmann tube-piercing method. In the case of the electric light bulb the design concept came first, derived from logical use of scientific principles, followed b

Some Motions,s usually guided by three surfaces arranged in V-flat formation as in figure 31a, giving unique kinematic location so long as the loads are downwards. Where this is not certain, slides are often of dove-tail shape, with three fixed surfaces, the fourth being adjustable, as in figure 31b. If we provi

Bearings and Seals,section on flexure bearings, useful where small movements are involved. In instrument work, crossed-leaf springs form a friction-free and slack-free pivot for angular movements of a few degrees. The arrangement requires at least three springs for symmetry. Any loads which tend to compress the spring
