8216-468: The ground and the other at the Tarim Basin with a planned depth of 11,100 metres (36,400 ft). Drillers may sink a borehole using a drilling rig or a hand-operated rig. The machinery and techniques to advance a borehole vary considerably according to manufacturer, geological conditions, and the intended purpose. For offshore drilling floating units or platforms supported by the seafloor are used for

8320-703: The highest level of professional competencies and this is a peer-reviewed process. Once the IntPE title is awarded, the engineer can gain easier admission to national registers of a number of members jurisdictions for international practice. In Canada, engineering is a self-regulated profession. The profession in each province is governed by its own engineering association. For instance, in the Province of British Columbia an engineering graduate with four or more years of post graduate experience in an engineering-related field and passing exams in ethics and law will need to be registered by

8424-599: The holes varied, the drilling of a single well could last nearly one full decade. It was not up until the 19th century that Europe and the West would catch up and rival ancient Chinese borehole drilling technology. For many years, the world's longest borehole was the Kola Superdeep Borehole in Russia. From 2011 until August 2012 the record was held by the 12,345-metre (40,502 ft) long Sakhalin-I Odoptu OP-11 Well, offshore

8528-514: The invention of Portland cement . Applied science led to the development of the steam engine. The sequence of events began with the invention of the barometer and the measurement of atmospheric pressure by Evangelista Torricelli in 1643, demonstration of the force of atmospheric pressure by Otto von Guericke using the Magdeburg hemispheres in 1656, laboratory experiments by Denis Papin , who built experimental model steam engines and demonstrated

8632-450: The limitations imposed by practicality, regulation, safety and cost. The word engineer ( Latin ingeniator , the origin of the Ir. in the title of engineer in countries like Belgium and The Netherlands) is derived from the Latin words ingeniare ("to contrive, devise") and ingenium ("cleverness"). The foundational qualifications of a licensed professional engineer typically include

8736-471: The power systems, sensors, electronics, embedded software in electronics, and control circuitry. Finally, a software engineer would develop the software that makes the robot behave properly. Engineers that aspire to management engage in further study in business administration, project management and organizational or business psychology. Often engineers move up the management hierarchy from managing projects, functional departments, divisions and eventually CEOs of

8840-474: The power to weight ratio of steam engines made practical steamboats and locomotives possible. New steel making processes, such as the Bessemer process and the open hearth furnace, ushered in an area of heavy engineering in the late 19th century. One of the most famous engineers of the mid-19th century was Isambard Kingdom Brunel , who built railroads, dockyards and steamships. The Industrial Revolution created

8944-432: The public at large. Each engineering discipline and professional society maintains a code of ethics, which the members pledge to uphold. Depending on their specializations, engineers may also be governed by specific statute, whistleblowing, product liability laws, and often the principles of business ethics . Some graduates of engineering programs in North America may be recognized by the iron ring or Engineer's Ring ,

9048-418: The public or other businesses, or engage in practice of engineering unless the business entity is registered with the state's board of engineering, and the practice is carried on or supervised directly only by engineers licensed to engage in the practice of engineering. In some instances, some positions, such as a "sanitation engineer", does not have any basis in engineering sciences. Although some states require

9152-434: The rise of engineering as a profession in the 18th century, the term became more narrowly applied to fields in which mathematics and science were applied to these ends. Similarly, in addition to military and civil engineering, the fields then known as the mechanic arts became incorporated into engineering. Canal building was an important engineering work during the early phases of the Industrial Revolution. John Smeaton

9256-616: The same time, are addressed and introduced as Engineer , rather than Sir/Madam in speech or Mr./Mrs./Ms. ( G./Gng./Bb. in Filipino) before surnames. That word is used either in itself or before the given name or surname. As of 2022 , thirty two countries in Europe (including nearly all 27 countries of the EU) now recognise the title of "European Engineer" which permits the use of the pre-nominal title of "EUR ING" (always fully capitalised). Each country sets its own precise qualification requirement for

9360-426: The same with full cognizance of their design; or to forecast their behavior under specific operating conditions; all as respects an intended function, economics of operation and safety to life and property. Engineering has existed since ancient times, when humans devised inventions such as the wedge, lever, wheel and pulley, etc. The term engineering is derived from the word engineer , which itself dates back to

9464-406: The shafts and rooms were complete with a timber frame, ladders and iron tools. By the first century BC, Chinese craftsmen cast iron drill bits and drillers were able to drill boreholes up to 1,500 metres (4,900 ft) deep. By the eleventh century AD, the Chinese were able to drill boreholes up to 900 metres (3,000 ft) in depth. Drilling for boreholes was time-consuming and long. As the depth of

9568-412: The social sciences or humanities, also are required. Accreditation is the process by which engineering programs are evaluated by an external body to determine if applicable standards are met. The Washington Accord serves as an international accreditation agreement for academic engineering degrees, recognizing the substantial equivalency in the standards set by many major national engineering bodies. In

9672-444: The solution that best matches the requirements and needs. Their crucial and unique task is to identify, understand, and interpret the constraints on a design in order to produce a successful result. Good problem solving skills are an important asset for engineers. Engineers apply techniques of engineering analysis in testing, production, or maintenance. Analytical engineers may supervise production in factories and elsewhere, determine

9776-464: The state of mechanical arts during the Renaissance is given in the mining engineering treatise De re metallica (1556), which also contains sections on geology, mining, and chemistry. De re metallica was the standard chemistry reference for the next 180 years. The science of classical mechanics , sometimes called Newtonian mechanics, formed the scientific basis of much of modern engineering. With

9880-505: The term "engineer" varies across countries and continents. In the Indian subcontinent , Russia, Middle East, Africa, and China, engineering is one of the most sought-after undergraduate courses, for which entrance examinations are highly competitive. In Egypt, the educational system makes engineering the second-most respected profession in the country (after medicine); engineering colleges at Egyptian universities require extremely high marks on

9984-501: The title of engineer is regulated by law. In France, the term ingénieur (engineer) is not a protected title and can be used by anyone who practices this profession. However, the title ingénieur diplomé (graduate engineer) is an official academic title that is protected by the government and is associated with the Diplôme d'Ingénieur , which is a renowned academic degree in France. Anyone misusing this title in France can be fined

10088-414: The transition from charcoal to coke . These innovations lowered the cost of iron, making horse railways and iron bridges practical. The puddling process , patented by Henry Cort in 1784 produced large scale quantities of wrought iron. Hot blast , patented by James Beaumont Neilson in 1828, greatly lowered the amount of fuel needed to smelt iron. With the development of the high pressure steam engine,

10192-576: The use of a piston, which he published in 1707. Edward Somerset, 2nd Marquess of Worcester published a book of 100 inventions containing a method for raising waters similar to a coffee percolator . Samuel Morland , a mathematician and inventor who worked on pumps, left notes at the Vauxhall Ordinance Office on a steam pump design that Thomas Savery read. In 1698 Savery built a steam pump called "The Miner's Friend". It employed both vacuum and pressure. Iron merchant Thomas Newcomen , who built

10296-428: The use of the title (though they are all broadly equivalent). Holding the requisite qualification does not afford automatic entitlement. The title has to be applied for (and the appropriate fee paid). The holder is entitled to use the title in their passport. EUR INGs are allowed to describe themselves as professionally qualified engineers and practise as such in any of the 32 participating countries including those where

10400-623: Was a steam jack driven by a steam turbine , described in 1551 by Taqi al-Din Muhammad ibn Ma'ruf in Ottoman Egypt . The cotton gin was invented in India by the 6th century AD, and the spinning wheel was invented in the Islamic world by the early 11th century, both of which were fundamental to the growth of the cotton industry . The spinning wheel was also a precursor to the spinning jenny , which

10504-513: Was a key development during the early Industrial Revolution in the 18th century. The earliest programmable machines were developed in the Muslim world. A music sequencer , a programmable musical instrument , was the earliest type of programmable machine. The first music sequencer was an automated flute player invented by the Banu Musa brothers, described in their Book of Ingenious Devices , in

10608-402: Was created by engineers that have graduated from École Centrale Paris , École des Mines de Paris , École polytechnique or Télécom Paris . This was also the case after WWII when France had to be rebuilt. Before the "réforme René Haby " in the 1970s, it was very difficult to be admitted to such schools, and the French ingénieurs were commonly perceived as the nation's élite. However, after

10712-642: Was developed by the Greeks around the 4th century BC, the trireme , the ballista and the catapult . In the Middle Ages, the trebuchet was developed. The earliest practical wind-powered machines, the windmill and wind pump , first appeared in the Muslim world during the Islamic Golden Age , in what are now Iran, Afghanistan, and Pakistan, by the 9th century AD. The earliest practical steam-powered machine

10816-505: Was the first self-proclaimed civil engineer and is often regarded as the "father" of civil engineering. He was an English civil engineer responsible for the design of bridges, canals, harbors, and lighthouses. He was also a capable mechanical engineer and an eminent physicist . Using a model water wheel, Smeaton conducted experiments for seven years, determining ways to increase efficiency. Smeaton introduced iron axles and gears to water wheels. Smeaton also made mechanical improvements to
