Sosrobahu
Sosrobahu is a road construction technique which allows long stretches of flyovers to be constructed above existing major roads with minimum disruption to traffic. The technique was designed and invented by Indonesian engineer Tjokorda Raka Sukawati and involves the construction of the horizontal supports for the highway beside the existing road, which are then lifted and turned 90 degrees before being placed on the top of the vertical supports to form the flyover pylons. This technique is of considerable value in increasing road mileage in large cities where there is limited right-of-way for new roads and the closure of existing roads throughout the flyover's construction using normal techniques would impose significant economic costs. The term ''sosrobahu'' was derived from Old Javanese which means "thousand shoulders". Background By the 1980s, Jakarta was experiencing increased traffic congestion, and flyovers were seen as one solution to the improving transport infrastruct ...

Friction
Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: *Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact. Dry friction is subdivided into ''static friction'' ("stiction") between non-moving surfaces, and ''kinetic friction'' between moving surfaces. With the exception of atomic or molecular friction, dry friction generally arises from the interaction of surface features, known as asperities (see Figure 1). *Fluid friction describes the friction between layers of a viscous fluid that are moving relative to each other. *Lubricated friction is a case of fluid friction where a lubricant fluid separates two solid surfaces. *Skin friction is a component of drag, the force resisting the motion of a fluid across the surface of a body. *Internal friction is the force resisting motion between the elements making up a so ...

Ramayana
The ''Rāmāyana'' (; sa, रामायणम्, ) is a Sanskrit literature, Sanskrit Indian epic poetry, epic composed over a period of nearly a millennium, with scholars' estimates for the earliest stage of the text ranging from the 8th to 4th centuries BCE, and later stages extending up to the 3rd century CE. ''Ramayana'' is one of the two important epics of Hinduism, the other being the ''Mahabharata, Mahābhārata''. The epic, traditionally ascribed to the Maharishi Valmiki, narrates the life of Sita, the Princess of Janakpur, and Rama, a legendary prince of Ayodhya city in the kingdom of Kosala. The epic follows his fourteen-year exile to the forest urged by his father King Dasharatha, on the request of Rama's stepmother Kaikeyi; his travels across forests in the South Asia, Indian subcontinent with his wife Sita and brother Lakshmana, the kidnapping of Sita by Ravana – the king of Lanka, that resulted in war; and Rama's eventual return to Ayodhya to be crowned kin ...

Kartavirya Arjuna
Kartavirya Arjuna ( sa, कार्तवीर्य अर्जुन, ; also known as Sahasrabahu Arjuna or Sahasrarjuna) was a king of an ancient Haihayas kingdom with capital at Mahishmati which is on the banks of Narmada River in the current state of Madhya Pradesh. Kartavirya was son of Kritavirya, king of the Haihayas. According to the Puranas, Haihaya was the grandson of Sahasrajit, son of Yadu. This is his patronymic, by which he is best known; he is also referred to simply as Arjuna. He is described as having a thousand hands and a great devotee of god Dattatreya. One of the several such accounts states that Arjuna conquered Mahishmati city from Karkotaka Naga, a Naga chief and made it his fortress-capital.Pargiter, F.E. (1972) 922 ''Ancient Indian Historical Tradition'', Delhi: Motilal Banarsidass, p.265-7 Almost 100 manuscripts on the worship of Kārtavīrya have been found mostly in the royal libraries of the Hindu Rajas.

Suharto
Suharto (; ; 8 June 1921 – 27 January 2008) was an Indonesian army officer and politician, who served as the second and the longest serving president of Indonesia. Widely regarded as a military dictator by international observers, Suharto led Indonesia through a dictatorship for 31 years, from the fall of Sukarno in 1967 until his own resignation in 1998. The legacy of his 31-year rule, and his US$38 billion net worth, is still debated at home and abroad. Suharto was born in the small village of Kemusuk, in the Godean area near the city of Yogyakarta, during the Dutch colonial era. He grew up in humble circumstances. His Javanese Muslim parents divorced not long after his birth, and he lived with foster parents for much of his childhood. During the Japanese occupation era, Suharto served in the Japanese-organized Indonesian security forces. During Indonesia's independence struggle, he joined the newly formed Indonesian Army. There, Suharto rose to the rank of major g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megapascal
The pascal (symbol: Pa) is the unit of pressure in the International System of Units (SI), and is also used to quantify internal pressure, stress, Young's modulus, and ultimate tensile strength. The unit, named after Blaise Pascal, is defined as one newton per square metre and is equivalent to 10 barye (Ba) in the CGS system. The unit of measurement called standard atmosphere (atm) is defined as 101,325 Pa. Common multiple units of the pascal are the hectopascal (1 hPa = 100 Pa), which is equal to one millibar, and the kilopascal (1 kPa = 1000 Pa), which is equal to one centibar. Meteorological observations typically report atmospheric pressure in hectopascals per the recommendation of the World Meteorological Organization, thus a standard atmosphere (atm) or typical sea-level air pressure is about 1013 hPa. Reports in the United States typically use inches of mercury or millibars (hectopascals). In Canada these reports are given in kilopascals. ...

Kilogram-force
The kilogram-force (kgf or kgF), or kilopond (kp, from la, pondus, lit=weight), is a non-standard gravitational metric unit of force. It does not comply with the International System of Units (SI) and is deprecated for most uses. The kilogram-force is equal to the magnitude of the force exerted on one kilogram of mass in a gravitational field (standard gravity, a conventional value approximating the average magnitude of gravity on Earth). That is, it is the weight of a kilogram under standard gravity. Therefore, one kilogram-force is by definition equal to .NISTbr>''Guide for the Use of the International System of Units (SI)''Special Publication 811, (1995) page 51 Similarly, a gram-force is , and a milligram-force is . Kilogram-force is a non-standard unit and is classified in the International System of Units (SI) as a unit that is not accepted for use with SI.

Pipe (material)
A pipe is a tubular section or hollow cylinder, usually but not necessarily of circular cross-section, used mainly to convey substances which can flow — liquids and gases (fluids), slurries, powders and masses of small solids. It can also be used for structural applications; hollow pipe is far stiffer per unit weight than solid members. In common usage the words ''pipe'' and ''tube'' are usually interchangeable, but in industry and engineering, the terms are uniquely defined. Depending on the applicable standard to which it is manufactured, pipe is generally specified by a nominal diameter with a constant outside diameter (OD) and a schedule that defines the thickness. Tube is most often specified by the OD and wall thickness, but may be specified by any two of OD, inside diameter (ID), and wall thickness. Pipe is generally manufactured to one of several international and national industrial standards. While similar standards exist for specific industry applicati ...

Rubber
Rubber, also called India rubber, latex, Amazonian rubber, ''caucho'', or ''caoutchouc'', as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds. Thailand, Malaysia, and Indonesia are three of the leading rubber producers. Types of polyisoprene that are used as natural rubbers are classified as elastomers. Currently, rubber is harvested mainly in the form of the latex from the rubber tree (''Hevea brasiliensis'') or others. The latex is a sticky, milky and white colloid drawn off by making incisions in the bark and collecting the fluid in vessels in a process called "tapping". The latex then is refined into the rubber that is ready for commercial processing. In major areas, latex is allowed to coagulate in the collection cup. The coagulated lumps are collected and processed into dry forms for sale. Natural rubber is used extensively in many applications and products, either alone or in combination wit ...

Lubricating
Lubrication is the process or technique of using a lubricant to reduce friction and wear and tear in a contact between two surfaces. The study of lubrication is a discipline in the field of tribology. Lubrication mechanisms such as fluid-lubricated systems are designed so that the applied load is partially or completely carried by hydrodynamic or hydrostatic pressure, which reduces solid body interactions (and consequently friction and wear). Depending on the degree of surface separation, different lubrication regimes can be distinguished. Adequate lubrication allows smooth, continuous operation of machine elements, reduces the rate of wear, and prevents excessive stresses or seizures at bearings. When lubrication breaks down, components can rub destructively against each other, causing heat, local welding, destructive damage and failure. Lubrication mechanisms Fluid-lubricated systems As the load increases on the contacting surfaces, distinct situations can be observed wit ...
