The origin of the lowly Phillips screw is an interesting one.
The history of metal fasteners go back to the 15th century. British toolmaker Joseph Whitworth devised the first screw in 1841 and American engineer produced the same in 1864.
Screws were very hard to produce, however, and required the manufacture of a conical helix.. The brothers Job and William Wyatt found a way to produce a screw on a novel machine that first cut the slotted head, and then cut the helix. Though their business...
Fuel economy for vehicles (city, highway and combined) is measured under controlled conditions in a laboratory using a series of tests specified by federal law.The results are displayed for the consumer on the "new car window sticker."
Estimating MPG with Laboratory Tests
In the laboratory, the vehicle's drive wheels are placed on a machine called a dynamometer. The "dyno" simulates the driving environment much like an exercise bike simulates cycling.
Engineers adjust the amount of energy...
In the late 60s/early 70s, Dodge was already offering some of the hottest cars of the muscle car era- awesome machines like the Hemi Challenger and 440 Six-Pack Super Bee. Designers, however, decided to rev up the cars’ visuals to match, creating a far-out assortment of vibrant exterior paint colors.
