Description: The history of civilisation almost parallels the ever-widening and ever-wiser use of machines. But, as we learn in this book, no matter how complex the machines of today appear, they are really a combination of two or more of the six simpler ones – the lever, the inclined plane, the screw, the wheel and axle, and the pulley.
It is these simple machines which mankind, through the ages, has learned to use in a great variety of ways which help it to do its work more easily. This book, like others in this exciting series, includes several interesting experiments. By performing these experiments, children will discover some of the laws of mechanics for themselves, and see why it is that we depend on machines to do so much of the world's work.
Lavishly illustrated with a mix of full-colour, two-tone monochrome, and b&w paintings and ink drawings – many of which are full-page (including a superb illustration of a late-'50s GMC truck).
Pictorial covers have a few negligible pockmarks on the front cover and a tiny crease on the rear cover, but are otherwise as new. The pages are in excellent condition: lightly tanned, but completely free from foxing or other marking. All illustrations remain super-bright.
Although the copyright date is given as 1960, this is likely to be a reprint from c.1966, as that is when a number of the titles listed on the rear were first published.
Measures 27.5 cm × 20.5 cm (11″ × 8.2″). Large 4to. 48 pp.
