Kareela (ferry)
''Kareela'' was a "Sydney K-class ferry, K-class" ferry on Port Jackson, Sydney Harbour. Launched in 1905, the double-ended timber-hulled steamer was built for Sydney Ferries Limited in response to the early twentieth century boom in cross-harbour ferry travel prior to the opening of the Sydney Harbour Bridge. She was the first of Sydney Ferries Limited's boats to have a fully enclosed upper deck. She survived the 1932 opening of the Sydney Harbour Bridge when many ferries were removed from service, and also the early 1950s rationalisation of the fleet following its takeover by the Government of New South Wales. Nicknamed "The Box", she had a relatively incident free career apart from a collision with a wharf that killed three of her passengers. She was sold in 1959 and broken up. "Kareela" is thought to be an Aboriginal Australians, Australian Aboriginal word meaning "south wind".

Sydney Ferries Limited
Sydney Ferries Limited operated ferry services on Port Jackson, Sydney Harbour from 1900 until June 1951. The company grew out of the North Shore Steam Ferry Company and took over smaller ferry operators to become the largest ferry operator in Sydney's history. Without a physical connection across the harbour, demand for ferry services to developing areas on the North Shore rose dramatically and Sydney Ferries commissioned 27 large ferries in its own right between 1900 and 1922. The company named its vessels with Australian Aboriginal words beginning with "K". The 1932 opening of the Sydney Harbour Bridge saw the companies annual patronage drop from 40 million to 15 million. Nineteenth century beginnings The first regular passenger ferry services across the harbour began in the 1840s and 1850s, at which time the Gerrard Brother's ran paddle steamers ''Ferry Queen'', ''Brothers (ferry), Brothers'', and ''Agenoria''. ''PS Herald, Herald'' was sent out from England for the North ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Knee (construction)
In woodworking, a knee is a natural or cut curved piece of wood. Knees, sometimes called ship's knees, are a common form of bracing in boat building and occasionally in timber framing. A knee rafter in carpentry is a bent rafter used to gain head room in an attic. Strength characteristics Wood is a highly anisotropic material (its strength varies considerably with the direction of applied force, i.e., parallel, radial, or tangential to the grain). Because wood is strongest when loaded in tension or compression along the grain, the best knees are those in which the wood grain follows the bend. For a knee with relatively little bend, it may be possible to cut the knee out of a single straight-grained board and still achieve sufficient strength. However, with increasing bend this method becomes problematic since more and more of the knee is aligned across the grain and is therefore considerably weaker. A knee laid out this way might easily snap in two under hand pressure alone, even ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Depression
The Great Depression was a severe global economic downturn from 1929 to 1939. The period was characterized by high rates of unemployment and poverty, drastic reductions in industrial production and international trade, and widespread bank and business failures around the world. The economic contagion began in 1929 in the United States, the largest economy in the world, with the devastating Wall Street stock market crash of October 1929 often considered the beginning of the Depression. Among the countries with the most unemployed were the U.S., the United Kingdom, and Weimar Republic, Germany. The Depression was preceded by a period of industrial growth and social development known as the "Roaring Twenties". Much of the profit generated by the boom was invested in speculation, such as on the stock market, contributing to growing Wealth inequality in the United States, wealth inequality. Banks were subject to laissez-faire, minimal regulation, resulting in loose lending and wides ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cremorne Point
Cremorne Point is a harbourside suburb on the Lower North Shore of Sydney, New South Wales, Australia located six kilometres north of the Sydney central business district, in the local government area of North Sydney Council. Cremorne Point shares the postcode of 2090 with Cremorne, a separate suburb to the north. Cremorne Point sits on Sydney Harbour between Shell Cove and Mosman Bay. Etymology Cremorne Point was named after the Cremorne Gardens in London, a popular pleasure ground in England, which derives from Gaelic words meaning 'boundary' and 'chieftain'. Robertsons Point was named after James Robertson who was granted 35 hectares there in 1820. He was the father of Premier Sir John Robertson. History Wooloorigang / Cremorne Point and Mosman Bay were both once Cammeraygal territory named Wul-warra-Jeung before European settlement in Sydney Cove to their south. Aborigines called the waters east of the point Goram-Bullagong. In early European settlement after 1788, it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Mosman Ferry Wharf
South Mosman ferry wharf is located on the northern side of Sydney Harbour serving the Lower North Shore suburb of Mosman. It is located at the end of Musgrave St, and was known as Musgrave Street Wharf from the 19th century through to the 1990s when the State Government renamed it "Mosman South". Today it is known as South Mosman but many locals still refer to it as Musgrave Street wharf. From the 3rd of June 2024 to the 24th of January 2025, South Mosman wharf was temporally closed while the wharf was rebuilt to include a new lift, stairs and a new floating pontoon with a covered waiting area. Services South Mosman wharf is served by Sydney Ferries Sydney Ferries is the public transport ferry network serving the city of Sydney, New South Wales.

The Australian Star
''The Australian Star'' was a daily English-language newspaper published in Sydney, Orange, New South Wales, New South Wales, Australia, from 1887 to 1909. It was published as ''The Star'', also known as ''The Star: the Australian Evening Daily'', until 1910 and then renamed ''The Sun (Sydney), The Sun'', which continued publication until 1988. History Promoted as the "new Protectionist evening paper", ''The Australian Star'' was first published on Thursday 1 December 1887 by Arthur Smyth, at the offices of the Australian Newspaper Company, 78 King Street, Sydney. The founding editor was William Henry Traill, W. H. Traill, a strong protectionist who later represented the electorate of South Sydney in the New South Wales Legislative Assembly. From 12 March 1909 the masthead became ''The Star: the Australian Evening Daily.'' In 1910, the business of the Australian Newspaper Company, including ''The Star'' and ''The Sunday Sun'', was acquired by Hugh Denison's newly registere ...

Stroke (engine)
In the context of an internal combustion engine, the term stroke has the following related meanings: * A phase of the engine's cycle (e.g. compression stroke, exhaust stroke), during which the piston travels from top to bottom or vice versa. * The type of power cycle used by a piston engine (e.g. two-stroke engine, four-stroke engine). * "Stroke length", the distance travelled by the piston during each cycle. The stroke length, along with bore diameter, determines the engine's displacement. Phases in the power cycle Commonly used engine phases or strokes (i.e. those used in a four-stroke engine) are described below. Other types of engines can have very different phases. Induction-intake stroke The induction stroke is the first phase in a four-stroke (e.g. Otto cycle or Diesel cycle) engine. It involves the downward movement of the piston, creating a partial vacuum that draws an air-fuel mixture (or air alone, in the case of a direct injection engine) into the combustion ...

Condensing Steam Locomotive
A condensing steam locomotive is a type of locomotive designed to recover exhaust steam, either in order to improve range between taking on boiler water, or to reduce emission of steam inside enclosed spaces. The apparatus takes the exhaust steam that would normally be used to produce a draft for the firebox, and routes it through a heat exchanger, into the boiler water tanks. Installations vary depending on the purpose, design and the type of locomotive to which it is fitted. It differs from the usual closed cycle condensing steam engine, in that the function of the condenser is primarily either to recover water, or to avoid excessive emissions to the atmosphere, rather than maintaining a vacuum to improve both efficiency and power. Thermodynamics Unlike the surface condenser often used on a steam turbine or marine steam engine, the condensing apparatus on a steam locomotive does not normally increase the power output, rather it may decrease considerably due to a reduction ...

Knot (unit)
The knot () is a unit of speed equal to one nautical mile per hour, exactly (approximately or ). The ISO standard symbol for the knot is kn. The same symbol is preferred by the Institute of Electrical and Electronics Engineers ( IEEE), while kt is also common, especially in aviation, where it is the form recommended by the International Civil Aviation Organization ( ICAO). The knot is a non- SI unit. The knot is used in meteorology, and in maritime and air navigation. A vessel travelling at 1 knot along a meridian travels approximately one minute of geographic latitude in one hour. Definitions ;1 international knot = :1 nautical mile per hour (by definition), : (exactly), : (approximately), : (approximately), : (approximately) : (approximately). The length of the internationally agreed nautical mile is . The US adopted the international definition in 1954, having previously used the US nautical mile (). The UK adopted the international nautical mile defi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triple Expansion
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed by a connecting rod and crank into rotational force for work. The term "steam engine" is most commonly applied to reciprocating engines as just described, although some authorities have also referred to the steam turbine and devices such as Hero's aeolipile as "steam engines". The essential feature of steam engines is that they are external combustion engines, where the working fluid is separated from the combustion products. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In general usage, the term ''steam engine'' can refer to either complete steam plants (including boilers etc.), such as railway steam locomotives and portable engines, or may refer to the piston or turbine machinery alone, ...

Companionway
In the architecture of a ship, a companion or companionway is a raised and windowed hatchway in the ship's deck, with a ladder leading below and the hooded entrance-hatch to the main cabins. A companionway may be secured by doors or, commonly in sailboats, ''hatch boards'' which fit in grooves in the companionway frame. This allows the lowest board to be left in place during inclement weather to minimize water infiltration. The term may be more broadly used to describe any ladder between decks.

Bridge (nautical)
A bridge (also known as a command deck), or wheelhouse (also known as a pilothouse), is a room or platform of a ship, submarine, airship, or spacecraft, spaceship from which the ship can be commanded. When a ship is under way, the bridge is manned by an Watchstanding, officer of the watch aided usually by an Able Seaman (occupation), able seaman acting as a lookout. During critical maneuvers the Captain (naval), captain will be on the bridge, often supported by an officer of the watch, an able seaman on the wheel and sometimes a Maritime pilot, pilot, if required.
