Former

A former is a structural member of an aircraft fuselage, of which a typical fuselage has a series from the nose to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft.

The Former-and-Longeron technique was adopted from boat construction (also called stations and stringers), and was typical of light aircraft built until the advent of structural skins such as fiberglass and other composite materials. Many of today's light aircraft, and homebuilt aircraft in particular, are still designed in this way.

They are also found in the cores of potentiometers in which the resistive material is wrapped round.

Notes

President of Mexico

The President of the United Mexican States (Spanish: Presidente de los Estados Unidos Mexicanos) is the head of state and government of Mexico. Under the Constitution, the president is also the Supreme Commander of the Mexican armed forces. The current President is Enrique Peña Nieto, who took office on December 1, 2012.

Currently, the office of the President is considered to be revolutionary, in that the powers of office are derived from the Revolutionary Constitution of 1917. Another legacy of the Revolution is its ban on re-election. Mexican presidents are limited to a single six-year term, called a sexenio. No one who has held the post, even on a caretaker basis, is allowed to run or serve again. The constitution and the office of the President closely follow the presidential system of government.

Requirements to hold office

Chapter III of Title III of the Constitution deals with the executive branch of government and sets forth the powers of the president, as well as the qualifications for the office. He is vested with the "supreme executive power of the Union."

Vicente Fox

Vicente Fox Quesada (Spanish pronunciation: [biˈsente ˈfoks keˈsaða]; born 2 July 1942) is a Mexican businessman who was President of Mexico from 1 December 2000, to 30 November 2006 under the National Action Party (PAN). He is also the Co-President of the Centrist Democrat International, an international organization of Christian democratic political parties.

Fox was elected President of Mexico in the 2000 presidential election, a historically significant election that made him the first president elected from an opposition party since Francisco I. Madero in 1910 and the first one in 71 years to defeat, with 42 percent of the vote, the Institutional Revolutionary Party (PRI).

After serving as president of Mexico for six years, President Fox returned to his home state of Guanajuato, where he resides with his wife and family. Since leaving the presidency, Vicente Fox has been involved in public speaking and the development of the Vicente Fox Center of Studies, Library and Museum.

Donald Trump

Donald John Trump, Sr. (born June 14, 1946) is an American businessperson and media personality. He is the chairman and president of The Trump Organization and the founder of Trump Entertainment Resorts. Trump's career, branding efforts, personal life, wealth, and outspoken manner have made him famous throughout the country. Since 2015, he is also a candidate for the Republican nomination for President of the United States in the 2016 election.

Trump is a native of New York City and a son of Fred Trump, who inspired him to enter real estate development. After two years at Fordham University and while studying at Wharton School of the University of Pennsylvania, Trump worked for his father's firm, Elizabeth Trump & Son. Upon graduating in 1968 he joined the company, and in 1971 was given control, renaming the company "The Trump Organization". Since then he has built hotels, golf courses, and other properties, many of which bear his name. He is a major figure in the American business scene and has received prominent media exposure. The NBC reality show The Apprentice bolstered his fame, and his three marriages were extensively reported in tabloids.
