A slide rule is a hand -operated mechanical calculator consisting of slidable rulers for evaluating mathematical operations such as multiplication, division, exponents, roots, logarithms, and trigonometry. It is one of the simplest analog computers. [1] [2]
Slide rule, a device consisting of graduated scales capable of relative movement, by means of which simple calculations may be carried out mechanically. Typical slide rules contain scales for multiplying, dividing, and extracting square roots, and some also contain scales for calculating.
7 de jun. de 2023 · To use a slide rule to multiply 2 numbers together, move the decimal points for each number you are multiplying so they fall between the values of 1 and 10. Next, find the smaller number on the D scale and slide the C scale so the "1" on the far left lines up with the smaller number.
Apollo 11 - NASA's Lunar Lander space vehicle, with the crew Neil Armstrong, Buzz Aldrin and Michael Collins carried slide rules, for the first time in history, into space and onto the moon, July, 1969. The slide rule of choice was the aluminum pocket.
The slide rule made it easier to utilize the log relations by developing a number line on which the displacement of the numbers were proportional to their logs. The slide rule eased the addition of the two logarithmic displacements of the numbers, thus assisting with multiplication and division in calculations.
A slide rule, also known as a slide ruler or a slipstick, is an extremely complex ruler that functions as an analog computer. By sliding various components of the ruler to align with one another, a slide rule can compute products, roots, logarithms, and the result of trigonometric functions.
