Background:The Atwood machine (or Atwoods machine) was invented in 1784 by the English mathematician George Atwood as a laboratory experiment to verify the mechanical laws of motion with constant acceleration. Atwoods machine is a common classroom demonstration used to illustrate principles of classical mechanics.The ideal Atwood machine consists of two objects of mass m1 and m2, connected by an inextensible massless string over an ideal massless pulley.Both masses experience uniform acceleration. When m1 = m2, the machine is in neutral equilibrium regardless of the position of the weights.
Hall, William HenryHall was responsible for a significant publication in the middle of the 18th century The new royal encyclopedia; or, complete modern universal dictionary of arts and sciences on a new and improved plan . containing a digest and display of the whole theory and practice of the liberal and mechanical arts comprising a general repository of ancient and modern literature . including all the material information that is contained in Chamber s Cyclopedia, the Encyclopædia Britannica, and the French Encyclopædie . first published in 1788 going into many re-issues over the next 50 years.The three volume set contained 153 copper-plate prints and maps, including some folding maps. Contained many brief encyclopedic entries in alphabetical orders plus longer, mainly illustrated, sections (systems or treatises) on a variety of subjects: Aerology; Aerostation (hot air balloons); Agriculture; Algebra; Amphibiology; Anatomy; Annuities; Architecture; Arithmetic; Astronomy (includes plates of telescopes); Book-Keeping; Botany; Brewing; Chronology; Chymistry; Comparative Anatomy; Concology; Dialling; Distillation; Drawing; Earth; Earthquakes; Electricity; Entomology; Farriery; Fencing; Fluxions; Fortification; Gardening; Geography (this section includes six folding maps); Geometry; Globes; Grammar; Heraldry; Hydrostatics and Hydraulics (one plate included a diving bell); Icthyology; Knighthood; Logic; Mammalia (included a plate showing whales); Mechanics; Medicine; Mensuration and Gauging; Miscroscopic Apparatus (microscopes); Midwifery; Military Affairs; Music; Natural History; Naval Affairs; Navigation (includes a folding map showing Cooks voyages); Optics; Oratory; Ornithology; Peerage; Perspective; Pneumatics; Projectiles; Steam Engines; Surgery; Surveying; Trigonometry; Vermeology; Volcanos; and War. Hard to find a complete set, as many have been broken up for their handsome copper plate engravings and maps.
