The Google Chart API allows a variety of graphs to be created. Livegap Charts creates line, bar, spider, polar-area and pie charts, and can export them as images without needing to download any tools. Veusz is a free scientific graphing tool that can produce 2D and 3D plots. Users can use it as a module in Python.
Diagram illustrating the principles used by William Wallace's eidograph. The ancient Greek engineer Hero of Alexandria described pantographs in his work Mechanics. [1]In 1603, [2] Christoph Scheiner used a pantograph to copy and scale diagrams, and wrote about the invention over 27 years later, in "Pantographice seu Ars delineandi res quaslibet per parallelogrammum lineare seu cavum" (Rome 1631).
Ackermann geometry. The Ackermann steering geometry is a geometric arrangement of linkages in the steering of a car or other vehicle designed to solve the problem of wheels on the inside and outside of a turn needing to trace out circles of different radii. It was invented by the German carriage builder Georg Lankensperger in Munich in 1816 ...

Horizontal tubular vessel, strong enough to contain high-pressure steam in a harsh working environment; closed at either end by the firebox and tube plate. Usually well filled with water but with space for steam – produced by heat from the firebox and boiler tubes – to be above the water surface. [1][2][5][3]: 9.
A cam is a rotating or sliding piece in a mechanical linkage used especially in transforming rotary motion into linear motion. [1][2] It is often a part of a rotating wheel (e.g. an eccentric wheel) or shaft (e.g. a cylinder with an irregular shape) that strikes a lever at one or more points on its circular path.
t. e. The futures wheel is a method for graphical visualisation of direct and indirect future consequences of a particular change or development. It was invented by Jerome C. Glenn in 1971, when he was a student at the Antioch Graduate School of Education (now Antioch University New England). The Futures Wheel is a way of organizing thinking ...
A diagram of the device. Newman's Energy Machine was a DC motor which the inventor, Joseph Newman, claimed to produce mechanical power exceeding the electrical power being supplied to it. In 1979, Newman attempted to patent the device, but it was rejected by the United States Patent Office as being a perpetual motion machine. [1]
