Image by Chris Devers
Quoting Smithsonian National Air and Space Museum | Boeing B-29 Superfortress &quotEnola Gay&quot:

Boeing’s B-29 Superfortress was the most sophisticated propeller-driven bomber of World War II and the initial bomber to house its crew in pressurized compartments. Despite the fact that made to fight in the European theater, the B-29 located its niche on the other side of the globe. In the Pacific, B-29s delivered a assortment of aerial weapons: conventional bombs, incendiary bombs, mines, and two nuclear weapons.

On August six, 1945, this Martin-constructed B-29-45-MO dropped the initial atomic weapon used in combat on Hiroshima, Japan. Three days later, Bockscar (on show at the U.S. Air Force Museum close to Dayton, Ohio) dropped a second atomic bomb on Nagasaki, Japan. Enola Gay flew as the advance weather reconnaissance aircraft that day. A third B-29, The Fantastic Artiste, flew as an observation aircraft on both missions.

AC Cobra

Image by _ alt3 _
The AC Cobra, sold as the Ford/Shelby AC Cobra in the United States and often known colloquially as the Shelby Cobra in that country, is an American-engined British sports auto produ
ced intermittently given that 1962.

Like numerous British specialist manufacturers, AC Automobiles had been employing the Bristol straight-six engine in its modest-volume production, such as its AC Ace two-seater roadster. This had a hand-constructed physique with a steel tube frame, and aluminium physique panels that had been produced using English wheeling machines. The engine was a pre-Planet War II design and style of BMW which by the 1960s was considered dated. Bristol decided in 1961 to cease production of its engine and instead to use Chrysler 331 cu in (5.4 L) V8 engines. AC began utilizing the 2.6 litre Ford Zephyr engine in its cars. In September 1961, American automotive designer Carroll Shelby wrote to AC asking if they would build him a automobile modified to accept a V8 engine. AC agreed, provided a appropriate engine could be discovered. Shelby went to Chevrolet to see if they would offer him with engines, but not wanting to add competitors to the Corvette they mentioned no. Even so, Ford wanted a vehicle that could compete with the Corvette and they occurred to have a brand new engine which could be employed in this endeavor: Ford’s 260 in HiPo (4.2 L) engine – a new lightweight, thin-wall cast modest-block V8 tuned for high efficiency. Ford offered Shelby with two engines. In January 1962 mechanics at AC Vehicles in Thames Ditton, Surrey fitted the prototype chassis CSX2000 with a 260 ci Ford V8 borrowed from Ford in the UK the 221 ci was by no means sent. Even so, early engineering drawings had been titled &quotAC Ace 3.6&quot. Right after testing and modification, the engine and transmission were removed and the chassis was air-freighted to Shelby in Los Angeles on 2 February 1962. His team fitted it with an engine and transmission in much less than eight hours at Dean Moon’s shop in Santa Fe Springs, California, and started road-testing.

Traction.—Any traction engine has power enoughto propel itself more than the road and through the fields pro-vided the drive wheels do not slip. Consequently thematter of the wheels adhering to the ground is an im-portant part. Where the road surface is firm there is nodifficulty but in a soft field wonderful difficulty is experienceddue to the fact that the lugs of the drive wheels tear upthe earth and enable the drive wheels to move withoutmoving the engine. It is a typical belief that the driv^ewheel which has the sharpest lug is the a single which will

In almost all circumstances thisis not true, considering that the lug which is sharp is really apt to cutthrough the earth, while one particular which is dull or round anddoes not have such penetrating impact will pack the earthdown and as a result make far more resistance for itself whilepassing by means of the earth. Nearly each and every engine builderhas a style of lug of his own. Fig. 338 shows a newstyle of traction wheel which seems to be giving verygood final results.

The material composing the Titan gears manufactured bythe Atha Steel Casting Company, of Newark, N. J., is so difficult that it cannot be reduce by anytool steel yet-recognized. Allfinished surfaces, such asteeth and hub-fit, are ac-curately ground to tem-plates. Although the ma-terial is difficult, it is notbrittle on the contrary itis so hard that test pieceshave been bent coldthrough an angle of 180degrees with no showingfracture. The gear is madesolid with the teeth castin, then a special machinegrinds the periphery of theteeth to the accurate di-ameter. One more machinegrinds every tooth to themaster, while nonetheless one more machine grinds out the hub-match and faces each sides. A gray iron or soft steel hub is thenpressed in at a pressure of 35 to 4.5 tons per square inch,and is bored out to the suitable size for forcing on the axle.

The wisdomof this special committee later was indicated by the superiorjury of awards, which granted to Bitulithic the gold medalas the nearest approach to the best pavement. The James-town boulevard commission also chosen Bitulithic above allothers for the boulevard to the Jamestown, (Va.), expositiongrounds.
