The RMS value of a set of values (or a continuous-time waveform) is the square root of the arithmetic mean of the squares of the values, or the square of the function that defines the continuous waveform.
A rudder is a primary control surface used to steer a ship, boat, submarine, hovercraft, airship, or other vehicle that moves through a fluid medium (usually air or water). On an airplane, the rudder is used primarily to counter adverse yaw and p-factor and is not the primary control used to turn
Diagram of RMS Titanic showing the arrangement of the bulkheads in red. Compartments in the engineering area at the bottom of the ship are noted in blue. Names of decks are listed to the right (starting at top on Boat deck, going from A through F and ending on Lower deck at the waterline).
The navigation bridge of the Titanic. On the Titanic, the navigation bridge (or command bridge) was a superstructure where the ship's command was exercised.From this location, the officer on watch determined the ship's geographical position, gave all orders regarding navigation and speed, and received information about everything happening on board.
The rudder is a fundamental control surface which is typically controlled by pedals rather than at the stick. It is the primary means of controlling yaw—the rotation of an airplane about its vertical axis. The rudder may also be called upon to counter-act the adverse yaw produced by the roll-control surfaces.
Finally the rudder is put the other way, as if trying to tack back again. Without the drive of the jib, she cannot do this and will stop hove to. This method is fast to implement and is recommended by sail training bodies such as the RYA as a "quick stop" reaction to a man overboard emergency, for sailing boats that have an engine available for ...
An azimuth thruster is a configuration of marine propellers placed in pods that can be rotated to any horizontal angle , making a rudder redundant. These give ships better maneuverability than a fixed propeller and rudder system.
The Titanic made a turn by rotating one-third of the way from the bow, which caused her rudder to hard over and crushed her starboard side into an iceberg. This would have caused the ship to flood, capsize, and sink within minutes, damaging the starboard side of the hull and potentially the superstructure.
