The cubic inch is a unit of measurement for volume in the Imperial units and United States customary units systems. It is the volume of a cube with each of its three dimensions (length, width, and depth) being one inch long.
The cubic inch and the cubic foot are still used as units of volume in the United States, although the common SI units of volume, the liter, milliliter, and cubic meter, are also used, especially in manufacturing and high technology.
Engine displacement is the volume swept by all the pistons inside the cylinders of a reciprocating engine in a single movement from top dead centre (TDC) to bottom dead centre (BDC). It is commonly specified in cubic centimetres (cc), litres (l), or (mainly in North America) cubic inches (CID). Engine displacement does not include the total volume of the combustion chamber.
A cubic centimetre (or cubic centimeter in US English) (SI unit symbol: cm3; non-SI abbreviations: cc and ccm) is a commonly used unit of volume that extends the derived SI-unit cubic metre, and corresponds to the volume of a cube that measures 1 cm × 1 cm × 1 cm. One cubic centimetre corresponds to a volume of 1⁄1,000,000 of a cubic metre, or 1⁄1,000 of a litre, or one millilitre; thus, 1 cm3 ≡ 1 ml. The mass of one cubic centimetre of water at 3.98 °C (the temperature at which it attains its maximum density) is closely equal to one gram. Note that SI supports only the use of symbols and deprecates the use of any abbreviations for units. Hence cm3 is preferred to cc or ccm.
Many scientific fields have replaced cubic centimeters with milliliters. The medical and automotive fields in the United States still use the term cubic centimetre. Much of the automotive industry outside the U.S. has switched to litres. The United Kingdom uses millilitres in preference to cubic centimetres in the medical field, but not the automotive. Most other English-speaking countries follow the UK example.
A metric engine is an American expression which refers to an internal combustion engine, often for automobiles, whose underlying engineering design is based on a metric system of units, particularly SI.
As American industry converted from traditional units to SI in the late 20th century, the automotive industry responded by transitioning its auto and engine designs to be "metric" rather than "English".
Suzuki AX 100 is a two-stroke, 100 cc motorcycle from Suzuki. It was made both in Japan and China. The Suzuki Samurai was a similar motorcycle made by Suzuki India for Indian market. Various Chinese companies copied the design and produced mechanical copies under various names such as Dayun. Launched in the middle 1990’s purely for the Far Eastern commuter market, in fact it is still made in China some 15 years on. It is the height of simplicity; a four-speed air-cooled two stroke with piston porting and a simple carburetor. A full chain guard and simple drum brakes keep maintenance tasks simple for unskilled labour, and parts inexpensive to buy, especially as they are manufactured by many different companies in China, many of poor or at best indifferent quality
A disaster is a natural or man-made (or technological) hazard resulting in an event of substantial extent causing significant physical damage or destruction, loss of life, or drastic change to the environment. A disaster can be ostensively defined as any tragic event stemming from events such as earthquakes, floods, catastrophic accidents, fires, or explosions. It is a phenomenon that can cause damage to life and property and destroy the economic, social and cultural life of people.
In contemporary academia, disasters are seen as the consequence of inappropriately managed risk. These risks are the product of a combination of both hazard/s and vulnerability. Hazards that strike in areas with low vulnerability will never become disasters, as is the case in uninhabited regions.
A social issue (also called a social problem or a social situation) is an issue that relates to society's perception of a person's personal lives. Different cultures have different perceptions and what may be "normal" behavior in one society may be a significant social issue in another society. Social issues are distinguished from economic issues. Some issues have both social and economic aspects, such as immigration. There are also issues that don't fall into either category, such as wars.
Thomas Paine, in Rights of Man and Common Sense, addresses man's duty to "allow the same rights to others as we allow ourselves". The failure to do so causes the birth of a social issue.
