Cambering and elevation of the road above the water table enabled rain water to run off into ditches on either side.

A basic strip long and wide was prepared for the wide runway. There were shoulders each side; and consequently run-offs beyond the shoulders. After cambering, weak spots were reset, and finally paving machinery was used to lay the asphalt surface. The result was an engineering success of which the contractors were very proud; so accurate was the cambering that the wet surface of the runway dried out evenly on each side of the centre-line.

His road required only a rise of three inches from the edges to the center. Cambering and elevation of the road above the water table enabled rain water to run off into ditches on either side.

300px In aeronautics and aeronautical engineering, camber is the asymmetry between the two acting surfaces of an airfoil, with the top surface of a wing (or correspondingly the front surface of a propeller blade) commonly being more convex (positive camber). An airfoil that is not cambered is called a symmetric airfoil. The benefits of cambering were discovered and first utilized by George Cayley in the early 19th century.

Gambrel is a Norman English word, sometimes spelled gambol such as in the 1774 Boston carpenters' price book (revised 1800). Other spellings include gamerel, gamrel, gambril, gameral, gambering, cambrel, cambering, chambrelA New English Dictionary on Historical Principles: Founded Mainly ..., Volume 4. p. 36. referring to a wooden bar used by butchers to hang the carcasses of slaughtered animals. Butcher's gambrels, later made of metal, resembled the two-sloped appearance of a gambrel roof when in use.

Natural slopes in the Wadhurst Clay, like those in the Ashdown Formation, are known for their instability, especially where impermeable clays and impermeable silts and siltstones are interbedded. Instability, resulting in landslips, often occurs along shear surfaces and weaknesses that originally developed during the Late Devensian glaciation. Other common features include cambering, valley bulging and solifluction lobes. Landslips often occur at or close to the upper boundary of the Wadhurst Clay, which is shared with the overlying Tunbridge Wells Sand Formation.

In 1999, Brazilian engineer Gildo Beleski applied for a patent on an improved design for a three-wheel cambering vehicle with the US Patent Office. In 2000, he founded Trikke Tech in Southern California, shipping 100 frames from Brazil and assembling Trikkes in his garage. Trikke three-wheel carving vehicles officially went on the market in 2002, and Time magazine named it one of the best inventions of that year. Over half a million body-powered Trikkes have been sold.

The Trikke works by shifting body weight Two Trikkes Video of Trikke climbing a hill The Trikke ( ; also known as a wiggle scooter, scissor scooter, carver scooter, and Y scooter) is a chainless, pedalless, personal vehicle with a three-wheel frame. The rider stands on two foot platforms above the two rear wheels and steers the vehicle with handlebars attached to the lone front wheel. The cambering system is designed to provide a stable, three-point platform that lets the rider lean into turns while all three wheels remain in contact with the ground. There are several variations of the Trikke, from body-powered fitness machines, to battery-powered transportation and personal mobility vehicles.

The emphasis on manufacturing, especially that done under licence, became even more apparent following the imposition of a 20% duty on imported machine tools and reduced demand, both triggered by the Great Depression. There was much innovation and many of these advances were pioneering techniques that are now universal, although from a trading perspective things were dire for the companies. In particular, The Churchill Machine Tool Co successfully harnessed the utility of hydraulics in many aspects of its machinery and developed a cambering mechanism for grinding rollers used in, for example, the paper industry. In 1932 H H Asbridge's "Hydrauto" bearing was introduced: this aided precision positioning of a workpiece with almost no intervening film of lubrication.
