a=chord, b=thickness, thickness-to-chord ratio = b/a The F-104 wing has a very low thickness-to-chord ratio of 3.36%. In aeronautics, the thickness-to-chord ratio, sometimes simply chord ratio or thickness ratio, compares the maximum vertical thickness of a wing to its chord.
Miles per hour (mph, m.p.h., MPH, or mi/h) is a British imperial and United States customary unit of speed expressing the number of miles travelled in one hour. It is used in the United Kingdom , the United States , and a number of smaller countries, most of which are UK or US territories, or have close historical ties with the UK or US.
The decrease of the speed of sound with height is referred to as a negative sound speed gradient. However, there are variations in this trend above 11 km. In particular, in the stratosphere above about 20 km, the speed of sound increases with height, due to an increase in temperature from heating within the ozone layer. This produces a positive ...
A bar scale would also normally appear on the drawing. Colon may also be substituted with a specific, slightly raised ratio symbol U+2236 ∶ RATIO (∶), ie. "1∶100". Da Vinci's Vitruvian Man illustrates the ratios of the dimensions of the human body; a human figure is often used to illustrate the scale of architectural or engineering ...
Hull speed can be calculated by the following formula: where is the length of the waterline in feet, and is the hull speed of the vessel in knots. If the length of waterline is given in metres and desired hull speed in knots, the coefficient is 2.43 kn·m −½.
The Delaware judge considering whether a vote by Tesla shareholders reinstated Elon Musk's $56 billion pay package which the court had voided will try to issue a ruling this year, according to the ...

According to a study a human at 70 kg (150 lb) requires about 60 watts to walk at 5 km/h (3.1 mph) on firm and flat ground, [6] while according to a calculator at kreuzotter.de the same person and power output on an ordinary bicycle will travel at 15 km/h (9.3 mph), [7] so in these conditions the energy expenditure of cycling is about one-third ...
