SS Oceanic (1870)
SS ''Oceanic'' was the White Star Line's first liner and first member of the Oceanic-class; she was an important turning point in passenger liner design. Entering service in 1871 for Atlantic crossings, she was later chartered to Occidental and Oriental Steamship Company (O&O) in 1875. The ship provided passenger service for O&O in the Pacific until 1895 when she was sold for scrap. Design and construction ''Oceanic'' was built by Harland and Wolff in Belfast, and was launched on 27 August 1870, arriving in Liverpool for her maiden voyage on 26 February 1871. Powered by a combination of steam and sail, she had twelve boilers generating steam at 65 pounds-force per square inch (450 kPa) powering a single four cylinder compound steam engine, 2 x and 2 x , with a stroke of . A single funnel exhausted smoke. Four masts carried sail; square sails on the first three masts, and fore-and-aft sails on the mizzenmast, for a four-masted barque rig. The hull was constructe ...

Pounds-force Per Square Inch
The pound per square inch (abbreviation: psi) or, more accurately, pound-force per square inch (symbol: lbf/in2), is a unit of measurement of pressure or of stress based on avoirdupois units and used primarily in the United States. It is the pressure resulting from a force with magnitude of one pound-force applied to an area of one square inch. In SI units, 1 psi is approximately . The pound per square inch absolute (psia) is used to make it clear that the pressure is relative to a vacuum rather than the ambient atmospheric pressure. Since atmospheric pressure at sea level is around , this will be added to any pressure reading made in air at sea level. The converse is pound per square inch gauge (psig), indicating that the pressure is relative to atmospheric pressure. For example, a bicycle tire pumped up to 65 psig in a local atmospheric pressure at sea level (14.7 psi) will have a pressure of 79.7 psia (14.7 psi + 65 psi). When gauge pressure is referenced to some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SS Oceanic 1 (image 4)
The ''Schutzstaffel'' (; ; SS; also stylised with SS runes as ''ᛋᛋ'') was a major paramilitary organisation under Adolf Hitler and the Nazi Party in Nazi Germany, and later throughout German-occupied Europe during World War II. It began with a small guard unit known as the ''Saal-Schutz'' ("Hall Security") made up of party volunteers to provide security for party meetings in Munich. In 1925, Heinrich Himmler joined the unit, which had by then been reformed and given its final name. Under his direction (1929–1945) it grew from a small paramilitary formation during the Weimar Republic to one of the most powerful organisations in Nazi Germany. From the time of the Nazi Party's rise to power until the regime's collapse in 1945, the SS was the foremost agency of security, mass surveillance, and state terrorism within Germany and German-occupied Europe. The two main constituent groups were the ''Allgemeine SS'' (General SS) and ''Waffen-SS'' (Armed SS). The ''Allgemeine SS' ...
