What do you mean by slide rules?
: a manual device used for calculation that consists in its simple form of a ruler and a movable middle piece which are graduated with similar logarithmic scales.
What is slide rule Short answer?
The slide rule, or slipstick, is a mechanical analog computer. The slide rule is used mainly for multiplication and division, and also for “scientific” functions such as roots, logarithms and trigonometry, but usually not for addition or subtraction. There are many different styles of slide rules.
Are slide rules still made?
Though they’re no longer produced, the company still stocks around 1,200 or so and occasionally gets an order for some. Why would anyone still want to buy a slide rule, when inexpensive calculators are so readily available? According to Haase, slide rules are better suited to some functions than are calculators.
What are the example of slide rules?
A slide rule requires the user to separately compute the order of magnitude of the answer in order to position the decimal point in the results. For example, 1.5 × 30 (which equals 45) will show the same result as 1,500,000 × 0.03 (which equals 45,000).
When did slide rules stop being used?
Slide rules became increasingly popular in the 1950s and 1960s, before beginning to fall out of favor to pocket calculators, which, by the mid 1970s, had become affordable and were considered significantly easier to use by the masses. The last slide rule manufactured in the United States was produced on July 11, 1976.
Do you know how to use a slide rule?
Get a Slide Rule. And for you canadians eh.
How does a slide rule work?
A slide rule works by adding or subtracting the numerical exponents of numbers for multiplication or division, respectively. Thus, numbers to be multiplied or divided are converted to their logarithmic values and their exponents are added or subtracted. Then, the product or quotient is found by taking the antilog of the resulting exponent.
What are the different types of slide rules?
There are two main types of cylindrical slide rules: those with helical scales such as the Fuller, the Otis King and the Bygrave slide rule, and those with bars, such as the Thacher and some Loga models.
What replaced the slide rule?
A slide rule, one of the last vestiges of geek nerddom in the fifties and sixties, is a remarkable invention. Unfortunately, having been replaced by the electronic calculator, the slide rule has fallen into disuse, which is a shame because it is an excellent conceptual tool for visualizing how to do computations with logarithmic numbers.
