Some problems require the use of scales on both sides of the slide rule. These problems can be worked by simply turning the rule over and working the next part of the problem. Turn it back to the other side again as needed. No inaccuracies will enter your calculations. Nothing will be lost.
Problems are inserted for the student to solve. Answers to problems are given at the end of the book. This section is devoted to those operations most often effected by slide rules; those which every student must first learn, multiplication and division.
27 cze 2024 · Understanding Slide Rules. Download Article. 1. Notice the gaps between numbers. Unlike an ordinary ruler, the numbers on a slide rule scale aren't spaced on an even, linear scale. Instead, the numbers are spaced using a special "logarithmic" formula, closer together on one side than the other.
THE simple slide rule, consisting of two logarithmic scales drawn on strips of cardboard mentioned in Section 1 would, in actual practice, be inconvenient to use. Clearly the two scales should be linked together by some means, so that whilst they could be made to slide to and fro along one another, they would, when set, retain their positions ...
THE PRINCIPLE OF THE SLIDE RULE . Linear and non-linear scales - numbering of the scales - reading the scales - multiplication and division of simple numbers. The reader will agree that the arithmetical operations of addition and subtraction are less tedious to carry out than those of multiplication and division.
This self-guided course gives numeric examples of the basic calculations that a slide rule can do. Just follow the step-by-step instructions and you will be amazed by the power and versatility of the venerable Slipstick. Click on any of the images below to get a large, unmarked, blowup of each slide rule as shown in the problem.
The words "slide rule" may conjure up images of overwhelming complexity and technical detail for you, but the underlying concept is actually quite straightforward. At its heart, the slide rule is nothing more than a simple and elegant solution for solving basic mathematical calculations.
