Trussed Concrete Steel Company
The Trussed Concrete Steel Company was founded in 1903 by Julius Kahn, an engineer and inventor. Its headquarters were in Detroit, Michigan, and its steel factory was in Youngstown, Ohio. The long company name changed to a shortened version of "Truscon" for public relations. Julius brought his brother Albert into the company for his architectural skills. The company manufactured prefabricated products of reinforced concrete beams and steel forms for reinforced concrete floors and walls. This allowed floor plans to have longer spans than in conventional construction. The solid-slab reinforced concrete construction produced better shearing stresses. Larger walls could be built with fewer supports which meant larger exterior windows could be used for better sunlight and ventilation. Kahn invented and patented a unique reinforcement system technology, the Kahn system, that was stronger, more economical, and lighter than the then existing systems for building construction. It ...

Republic Steel
Republic Steel is an American steel manufacturer that was once the country's third largest steel producer. It was founded as the Republic Iron and Steel Company in Youngstown, Ohio in 1899. After rising to prominence during the early 20th Century, Republic suffered heavy economic losses and was eventually bought out before re-emerging in the early 2000s as a subsidiary. The company currently manufactures Special Bar Quality (SBQ) steel bars and employs around 2,000 people. It is currently owned by Grupo Simec, based in Guadalajara, Mexico. Corporate history Origins and rise to prominence In 1927, Cyrus S. Eaton acquired and combined Republic with several other small steel companies, with the goal of becoming large enough to rival U.S. Steel. The newly named Republic Steel Corporation was headquartered in Cleveland, Ohio, and became America's third largest steel company, trailing only U.S. Steel and Bethlehem Steel after acquiring Bourne-Fuller Company and the Central Alloy S ...

Shear Stress
Shear stress, often denoted by (Greek: tau), is the component of stress coplanar with a material cross section. It arises from the shear force, the component of force vector parallel to the material cross section. ''Normal stress'', on the other hand, arises from the force vector component perpendicular to the material cross section on which it acts. General shear stress The formula to calculate average shear stress is force per unit area.: : \tau = , where: : = the shear stress; : = the force applied; : = the cross-sectional area of material with area parallel to the applied force vector. Other forms Wall shear stress Wall shear stress expresses the retarding force (per unit area) from a wall in the layers of a fluid flowing next to the wall. It is defined as: \tau_w:=\mu\left(\frac\right)_ Where \mu is the dynamic viscosity, u the flow velocity and y the distance from the wall. It is used, for example, in the description of arterial blood flow in which case which ther ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stair Tread
A stair tread is the horizontal portion of a set of stairs on which a person walks. The tread can be composed of wood, metal, plastic, or other materials. In residential settings, treads can be covered in carpeting. Stair treads can come in non-slip varieties, particularly in commercial or industrial locations. Styles of tread There are a number of different styles of tread: Mid flight treads. ;Straight or flier.: A standard oblong shaped tread. used in a straight flight. ;Diminishing flier.: Set into the straight section of flight before a turn, with one end narrower than the other Used to change the pitch of the handrail before a 180º turn. ;Winder.: wider at one end, used to turn the flight. ;Kite winder.: A quadrilateral shaped tread, used in the corner of a turn: hence the kite name. Feature or starting treads. These treads are used to embellish the start of a flight of stairs, they may have either a straight front to them or a commode/curved front to enhance them furthe ...

Jamaica
Jamaica (; ) is an island country situated in the Caribbean Sea. Spanning in area, it is the third-largest island of the Greater Antilles and the Caribbean (after Cuba and Hispaniola). Jamaica lies about south of Cuba, and west of Hispaniola (the island containing the countries of Haiti and the Dominican Republic); the British Overseas Territory of the Cayman Islands lies some to the north-west. Originally inhabited by the indigenous Taíno peoples, the island came under Spanish rule following the arrival of Christopher Columbus in 1494. Many of the indigenous people either were killed or died of diseases, after which the Spanish brought large numbers of African slaves to Jamaica as labourers. The island remained a possession of Spain until 1655, when England (later Great Britain) conquered it, renaming it ''Jamaica''. Under British colonial rule Jamaica became a leading sugar exporter, with a plantation economy dependent on the African slaves and later their des ...

San Francisco Earthquake
At 05:12 Pacific Standard Time on Wednesday, April 18, 1906, the coast of Northern California was struck by a major earthquake with an estimated moment magnitude of 7.9 and a maximum Mercalli intensity of XI (''Extreme''). High-intensity shaking was felt from Eureka on the North Coast to the Salinas Valley, an agricultural region to the south of the San Francisco Bay Area. Devastating fires soon broke out in San Francisco and lasted for several days. More than 3,000 people died, and over 80% of the city was destroyed. The events are remembered as one of the worst and deadliest earthquakes in the history of the United States. The death toll remains the greatest loss of life from a natural disaster in California's history and high on the lists of American disasters. Tectonic setting The San Andreas Fault is a continental transform fault that forms part of the tectonic boundary between the Pacific Plate and the North American Plate. The strike-slip fault is characterized by mai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mitsui & Co
is one of the largest ''sogo shosha'' (general trading companies) in Japan; it is part of the Mitsui Group. History The company was established in 1876 with 16 members including the founder, Takashi Masuda. As Japan's international trading was dominated by foreigners since the end of the Edo period, it aimed to expand business owned by Japanese citizens. By the end of World War II, it became a dominant trading giant, but was dissolved by the order of GHQ. The current Mitsui & Co. was established in 1947 as Daiichi Bussan Kaisha, Ltd. (''First Bussan Corporation Ltd''). In 1959, it merged with several other trading companies and changed its name to Mitsui & Co., Ltd. During Japan's period of rapid postwar economic growth, the firm was a key player in several major natural resources projects. In 1971, it took a stake in an offshore gas field near Das Island in Abu Dhabi, which supplies liquefied natural gas to Japan on an exclusive basis; it invested in a major Western Austra ...
