  2. Problems in Latin squares - Wikipedia

    en.wikipedia.org/wiki/Problems_in_Latin_squares

    In mathematics, the theory of Latin squares is an active research area with many open problems. As in other areas of mathematics, such problems are often made public at professional conferences and meetings. Problems posed here appeared in, for instance, the Loops (Prague) conferences and the Milehigh (Denver) conferences.

  3. Monty Hall problem - Wikipedia

    en.wikipedia.org/wiki/Monty_Hall_problem

    If the car is behind door 1, the host can open either door 2 or door 3, so the probability that the car is behind door 1 and the host opens door 3 is ⁠ 1 / 3 ⁠ × ⁠ 1 / 2 ⁠ = ⁠ 1 / 6 ⁠. If the car is behind door 2 – with the player having picked door 1 – the host must open door 3, such the probability that the car is behind door ...

    en.wikipedia.org/wiki/Slider-crank_linkage

    This inverted slider-crank is the form of a slider-crank linkage that is often used to actuate a hinged joint in construction equipment like a crane or backhoe, as well as to open and close a swinging gate or door. [2] [3] [4] A slider-crank is a four-bar linkage that has a crank that rotates coupled to a slider that the moves along a straight ...

    Circa-1960 Saab two-stroke engine 2010 Suzuki K10B engine. Among the first cars to use a straight-three engine is the 1953–1955 DKW F91, powered by a 900 cc (55 cu in) two-stroke engine, although this was predated by the 3 cylinder 15hp Rolls Royce produced in 1905 and a number of other cars of this era also used 3 cylinder engines.

  6. Three prisoners problem - Wikipedia

    en.wikipedia.org/wiki/Three_Prisoners_problem

    Hence C's chances are (⁠ 1 / 3 ⁠)/(⁠ 1 / 2 ⁠) = ⁠ 2 / 3 ⁠ and A's are (⁠ 1 / 6 ⁠)/(⁠ 1 / 2 ⁠) = ⁠ 1 / 3 ⁠. The key to this problem is that the warden may not reveal the name of a prisoner who will be pardoned. If we eliminate this requirement, it can demonstrate the original problem in another way.

  7. Door problem - Wikipedia

    en.wikipedia.org/wiki/Door_problem

    A door is an example of a complex feature that is seemingly trivial to implement correctly. In the original description of the analogy, Liz England justifies and explains the job requirements of a designer and how complex the job actually is compared to how the requirements are initially posed (making a door).

  8. Door closer - Wikipedia

    en.wikipedia.org/wiki/Door_closer

    A door closer is a mechanical device that regulates the speed and action of a door’s swing. [1] Manual closers store the force used to open the door in some type of spring and reuse it to close the door. Automatic types use electricity to regulate door swing behavior. Door closers can be linked to a building's fire and security alarm systems. [2]
