Q 01A visit to which Chicago industry's plants inspired the moving assembly line at Ford?
Meatpacking
Meatpacking plants ran what was called a disassembly line. Ford's William Klann saw one at Swift & Company and reversed the idea, so that a car came together step by step instead of coming apart.
Q 02Which Italian city's Arsenal could turn out nearly one war galley a day, centuries before car factories?
Venice
Venice fitted out galleys at its Arsenal with standardized parts on a production-line basis in the early 1500s. Galileo later advised its engineers as a consultant.
Q 03Imports from which country prompted an 1887 British origin-label law, only for the label to become a badge of quality?
Germany
Germany was where most of the falsely marked goods behind the Merchandise Marks Act came from. Instead of warning buyers off, the label grew into a brand synonymous with quality, durability and reliability.
Q 04Which small item did Adam Smith break into about eighteen steps to show the power of dividing labor?
Pins
Pins were Smith's example in The Wealth of Nations. He reckoned ten men sharing the tasks could make upwards of 48,000 a day, where each working alone could not have made twenty.
Q 05Taiichi Ohno based Toyota's just-in-time kanban system on the shelf restocking of which American businesses?
Supermarkets
Supermarkets stock only what they expect to sell, and shoppers take only what they need. Toyota began studying them in the late 1940s and carried their shelf-stocking techniques onto the factory floor.
Q 06Which snack, launched by Procter & Gamble, is cooked by a machine that novelist Gene Wolfe helped develop?
Pringles
Pringles are shaped from a potato-based dough into identical saddles, then fried and stacked in a tube. Wolfe was a mechanical engineer as well as an author of science-fiction and fantasy novels.
Q 07Which lightweight metal, once priced above gold, became commonplace after the Hall–Héroult process of 1886?
Aluminum
Aluminum was still uncommon in 1884, when a 2.85-kilogram piece of it capped the Washington Monument. Two years later Charles Martin Hall and Paul Héroult independently found how to produce it on an industrial scale.
Q 08Which American icon stands for the women who worked in factories and shipyards during World War II?
Rosie the Riveter
Rosie the Riveter took her name from a 1942 song. Norman Rockwell then painted her for a 1943 Saturday Evening Post cover, on her lunch break with a rivet gun across her lap.
Q 09Which technology, pioneered by Chuck Hull's stereolithography patent, does industry call additive manufacturing?
3D printing
3D printing builds a part by adding material layer by layer, where machining removes it. In the 1980s it was thought fit only for prototypes, and a machine cost upwards of $300,000.
Q 10The Jacquard loom of 1804 wove patterns automatically by reading which medium?
Punched cards
Punched cards were laced into a chain, each one standing for a single row of the design. A silk portrait woven from 24,000 of them helped inspire Charles Babbage's Analytical Engine.
Q 11Which Ford car of 1908 sold more than 15 million and made car travel affordable for middle-class Americans?
Model T
The Model T was not sold in black at all at first: until 1913 buyers chose gray, green, blue or red. Ford's famous black-only policy began in 1914.
Q 12Which American inventor signed a 1798 contract for army muskets and championed interchangeable parts?
Eli Whitney
Eli Whitney lost much of his cotton gin profit in patent lawsuits, so he turned to government gun contracts. His own muskets were still costly and handmade by skilled workmen.
Q 13Which process, patented by Charles Goodyear in 1844, toughens natural rubber by heating it with sulfur?
Vulcanization
Q 21Which English inventor's converter made the first cheap mass-produced steel by blowing air through molten pig iron?
Henry Bessemer
Henry Bessemer made his first fortune from steam-powered machines that turned out bronze powder for gold paint. He turned to steel while trying to cut the cost of military ordnance.
Q 22Which element, at 10.5 percent or more, makes steel stainless by forming a protective film that heals itself?
Chromium
Chromium forms a passive film that repairs itself whenever it meets oxygen. The alloy's name took years to settle: in 1921 one trade journal was calling it unstainable steel.
Q 23Hot-dip galvanizing protects steel from rust by submerging it in a molten bath of which metal?
Zinc
Vulcanization is named after Vulcan, the Roman god of fire. British inventor Thomas Hancock took out a British patent for the same treatment in 1843, before Goodyear had his American one.
Q 14Which movement of English textile workers wrecked factory machinery in organized raids from 1811 onward?
Luddites
Luddites signed their threatening letters to mill owners with the name of Ned Ludd, a legendary weaver. The government sent in the army, and the word came to mean anyone opposed to new technology.
Q 15Which chemical element is grown into single-crystal ingots and sliced into thin wafers for most computer chips?
Silicon
Silicon for chips is refined to a purity of 99.9999999 percent or higher. Each round wafer is cut from a crystal pulled out of a melt, a method devised by Polish chemist Jan Czochralski.
Q 16Which country, nicknamed the world's factory, overtook the United States as the top manufacturing nation by 2010?
China
China built that reputation on exports after joining the World Trade Organization in 2001. Within a decade it was producing more manufactured goods by value added than any other nation.
Q 17Which aircraft maker's factory in Everett, Washington, is the largest building in the world by volume?
Boeing
Boeing put up the Everett plant in 1967 to assemble the 747 jumbo jet. The main building encloses more than 472 million cubic feet, enough room to hold all of Disneyland.
Q 18Which pioneering robot arm joined a General Motors plant in 1961 and later putted a golf ball on The Tonight Show?
Unimate
Unimate was the first industrial robot, a 4,000-pound arm invented by George Devol. It moved hot die castings and welded them onto car bodies, work that could poison or maim a human.
Q 19Flat window glass is made in the Pilkington process by floating molten glass on a bath of which molten metal?
Tin
Tin has a low melting point, and floating the glass on it gives a sheet of uniform thickness with a very flat surface. Pilkington pioneered the technique in the 1950s at St Helens in England.
Q 20In which Charlie Chaplin film does the Tramp crack under the pace of an assembly line and get stuck in a machine?
Modern Times
Modern Times was Chaplin's last performance as the Little Tramp. He set the 1936 comedy in the Great Depression, with the factory's repetitive work driving his character to a nervous breakdown.
Zinc goes on protecting even where the coating is damaged, because it corrodes in place of the exposed steel. The process is named after the Italian scientist Luigi Galvani.
Q 24Which English city, a center of cutlery making since the 1600s, is where Harry Brearley developed stainless steel?
Sheffield
Sheffield metallurgist Harry Brearley was hunting for a gun-barrel steel that resisted erosion, not rust. He called his 1913 alloy rustless steel until a local cutlery maker gave it a catchier name.
Q 25Which machine tool did Henry Maudslay refine around 1800 so that it could cut standard screw threads into metal?
Lathe
The lathe is far older than the factory: a painting from 4th-century BC Egypt shows one. Maudslay's screw-cutting version allowed thread sizes to be standardized for the first time.
Q 26Which metalworking process shapes solid metal with compressive blows, as a blacksmith does with hammer and anvil?
Forging
Forging is one of the oldest known metalworking processes. Parts made this way have about a 20 percent higher strength-to-weight ratio than cast or machined ones of the same material.
Q 27Which fuel gas, burned with pure oxygen at about 3,500 °C, is the primary choice for gas welding torches?
Acetylene
Acetylene burns far hotter with oxygen than propane or hydrogen can manage. French engineers Edmond Fouché and Charles Picard were the first to develop welding with it, in 1903.
Q 28What does the N stand for in CNC, the system that lets a computer steer mills, routers and other cutting machines?
Numerical
Numerical control came first: machines of the 1940s and 1950s followed points fed in on tape. Adding a computer made the programs easier to write and change, usually as lines of G-code.
Q 29Which process, patented in an early form in 1872, is the most common way of making plastic parts?
Injection molding
Injection molding began with a machine that worked like a large hypodermic needle, its plunger forcing plastic through a heated cylinder into a mold. John Wesley Hyatt and his brother Isaiah patented it.
Q 30Which process, patented in 1797 for making metal pipe, also gives macaroni and many breakfast cereals their shape?
Extrusion
Extrusion pushes material through a die cut to the cross-section of the finished piece. It works on metals, polymers, ceramics, concrete and foodstuffs alike.
