Article: A servomotor is a motor, very often sold as a complete module, which is used within a position-control or speed-control feedback control system mainly control valves, such as motor-operated control valves. Servomotors are used in applications such as machine tools, pen plotters, and other process systems. Motors intended for use in a servomechanism must have well-documented characteristics for speed, torque, and power. The speed vs. torque curve is quite important and is high ratio for a servo motor. Dynamic response characteristics such as winding inductance and rotor inertia are also important; these factors limit the overall performance of the servomechanism loop. Large, powerful, but slow-responding servo loops may use conventional AC or DC motors and drive systems with position or speed feedback on the motor. As dynamic response requirements increase, more specialized motor designs such as coreless motors are used. AC motors' superior power density and acceleration characteristics compared to that of DC motors tends to favor PM synchronous, BLDC, induction, and SRM drive applications.

Question: What factors limit performance of servo motors?
Ans: winding inductance and rotor inertia


Here is a question about this article: During Andrés López Obrador's administration a political slogan was introduced: la Ciudad de la Esperanza ("The City of Hope"). This motto was quickly adopted as a city nickname, but has faded since the new motto Capital en Movimiento ("Capital in Movement") was adopted by the administration headed by Marcelo Ebrard, though the latter is not treated as often as a nickname in media. Since 2013, to refer to the City particularly in relation to government campaigns, the abbreviation CDMX has been used (from Ciudad de México).
What is the answer to this question: What is the nickname of the city that the government is trying to push now?
****
So... Capital en Movimiento


The problem: Answer a question about this article:
During regular, day-to-day activities, Somali women usually wear the guntiino, a long stretch of cloth tied over the shoulder and draped around the waist. It is usually made out of alandi, which is a textile common in the Horn region and some parts of North Africa. The garment can be worn in different styles. It can also be made with other fabrics, including white cloth with gold borders. For more formal settings, such as at weddings or religious celebrations like Eid, women wear the dirac. It is a long, light, diaphanous voile dress made of silk, chiffon, taffeta or saree fabric. The gown is worn over a full-length half-slip and a brassiere. Known as the gorgorad, the underskirt is made out of silk and serves as a key part of the overall outfit. The dirac is usually sparkly and very colorful, the most popular styles being those with gilded borders or threads. The fabric is typically acquired from Somali clothing stores in tandem with the gorgorad. In the past, dirac fabric was also frequently purchased from South Asian merchandisers.
What is the regular garment of Somali women?
****
The answer: the guntiino

Qing China reached its largest extent during the 18th century, when it ruled China proper (eighteen provinces) as well as the areas of present-day Northeast China, Inner Mongolia, Outer Mongolia, Xinjiang and Tibet, at approximately 13 million km2 in size. There were originally 18 provinces, all of which in China proper, but later this number was increased to 22, with Manchuria and Xinjiang being divided or turned into provinces. Taiwan, originally part of Fujian province, became a province of its own in the late 19th century, but was ceded to the Empire of Japan in 1895 following the First Sino-Japanese War. In addition, many surrounding countries, such as Korea (Joseon dynasty), Vietnam frequently paid tribute to China during much of this period. Khanate of Kokand were forced to submit as protectorate and pay tribute to the Qing dynasty in China between 1774 and 1798.

How many provinces were there at the height of Qing China?
Answer: 22


Greece's technology parks with incubator facilities include the Science and Technology Park of Crete (Heraklion), the Thessaloniki Technology Park, the Lavrio Technology Park and the Patras Science Park, the Science and Technology Park of Epirus (Ioannina). Greece has been a member of the European Space Agency (ESA) since 2005. Cooperation between ESA and the Hellenic National Space Committee began in the early 1990s. In 1994 Greece and ESA signed their first cooperation agreement. Having formally applied for full membership in 2003, Greece became the ESA's sixteenth member on 16 March 2005. As member of the ESA, Greece participates in the agency's telecommunication and technology activities, and the Global Monitoring for Environment and Security Initiative.
Greece and ESA signed their first agreement in what year?
1994
