Modern societies depend upon machines to provide standards of living far beyond the level that man alone can provide. The human body is very limited in its ability to generate large or very small forces and cannot work at high speeds or with high accuracy for long periods. To overcome these limitations man has striven to develop machines that augment his own strength and reduce the drudgery of repetitive tasks. We all now depend upon machines to provide us with our food, clothing, energy, transport, and defense. Most households, in addition to possessing some form of transport, have machines to reduce the effort involved in washing, cleaning, and preparing food. Agriculture and medicine depend on machines to increase their efficiency. Less familiar are the machines used on an industrial scale for knitting and weaving, for food processing and packaging, and for the manufacture of metal goods of all sorts.
