  2. Simple machine - Wikipedia

    en.wikipedia.org/wiki/Simple_machine

    A simple machine is a mechanical device that changes the direction or magnitude of a force. [1] In general, they can be defined as the simplest mechanisms that use mechanical advantage (also called leverage) to multiply force. [2]

  3. Collatz conjecture - Wikipedia

    en.wikipedia.org/wiki/Collatz_conjecture

    The power of 3 multiplying a is independent of the value of a; it depends only on the behavior of b. This allows one to predict that certain forms of numbers will always lead to a smaller number after a certain number of iterations: for example, 4a + 1 becomes 3a + 1 after two applications of f and 16a + 3 becomes 9a + 2 after four applications ...

  4. Arbitrary-precision arithmetic - Wikipedia

    en.wikipedia.org/wiki/Arbitrary-precision_arithmetic

    Arbitrary precision is used in applications where the speed of arithmetic is not a limiting factor, or where precise results with very large numbers are required. It should not be confused with the symbolic computation provided by many computer algebra systems, which represent numbers by expressions such as π·sin(2), and can thus represent ...

  5. Mechanical advantage device - Wikipedia

    en.wikipedia.org/wiki/Mechanical_advantage_device

    A simple machine that exhibits mechanical advantage is called a mechanical advantage device - e.g.: Lever: The beam shown is in static equilibrium around the fulcrum. This is due to the moment created by vector force "A" counterclockwise (moment A*a) being in equilibrium with the moment created by vector force "B" clockwise (moment B*b).

  6. Mechanical calculator - Wikipedia

    en.wikipedia.org/wiki/Mechanical_calculator

    This machine could add and subtract two numbers directly and multiply and divide by repetition. Since, unlike Schickard's machine, the Pascaline dials could only rotate in one direction zeroing it after each calculation required the operator to dial in all 9s and then (method of re-zeroing) propagate a carry right through the machine. [23]

  7. Pascal's calculator - Wikipedia

    en.wikipedia.org/wiki/Pascal's_calculator

    He designed the machine to add and subtract two numbers directly and to perform multiplication and division through repeated addition or subtraction. Pascal's calculator was especially successful in the design of its carry mechanism, which adds 1 to 9 on one dial, and carries 1 to the next dial when the first dial changes from 9 to 0. His ...

  8. Stepped reckoner - Wikipedia

    en.wikipedia.org/wiki/Stepped_reckoner

    There is also a tens-carry indicator and a control to set the machine to zero. The machine can: add or subtract an 8-digit number to/from a 16-digit number, multiply two 8-digit numbers to get a 16-digit result, divide a 16-digit number by an 8-digit divisor. Addition or subtraction is performed in a single step, with a turn of the crank.

  9. Talk:Simple machine - Wikipedia

    en.wikipedia.org/wiki/Talk:Simple_machine

    A spring is not a simple machine because it does not make work easier.If it simplified work then it would be considered a simple machine. a simple machine can be associated with springs like a rube goldberg machine. -Anna — Preceding unsigned comment added by 2604:6000:B7CE:1800:649E:C921:91BF:8E9F 00:56, 4 April 2017 (UTC) Right.
