Step 1: Design the Slide Rule. The first thing you'll need to do is design the rule. There are places on the internet that have templates for circular rules, but I wanted to design my own. It turned out that in the process, I learned a lot about how slide rules worked.
Apr 10, 2022 · log 10 x × 360°. Suppose you want to multiply x and y, and xy is less than 10, i.e. log 10 x + log 10 y < 1. Then the multiplication procedure works exactly analogously to how it would have with a straight slide rule. Line up the 1 of the inner ring with the position of x on the outer ring. The position of y on the inner ring lines up with xy ...
A-to-Z. Circular slide rules. Introduction. Although circular slide rules have some advantages over linear slide rules they were never as popular. The two main advantages of this type of slide rule are: They are more compact. A scale of 10 cm diameter has a length 30 cm. While calculating with a linear slide rules having a basic range of scales ...
New Circular Slide Rule. Multiplication. Of two given numbers Rule: Set 1 on scale C to multiply on scale D. Against the multiplier on scale C read the product on scale D. Example 1:1.8 x 2.5 = 4.5 Set on C to 1.8 on D. Against 2.5 on C read 4.5 on D.
Apr 14, 2007 · The slide rule is a simple but elegant mechanical calculator. A practiced user with a good quality slide rule can multiply, divide, exponentiate, take logarithms and perform trigonometric operations to three significant figures more quickly than with an electronic calculator. Below you will find a PostScript template and instructions for ...
Jul 8, 2021 · The circular slide rule is an analog calculating device invented in the U.K. in the 17th century. It was widely used until the 1970s. These step-by-step instructions were derived from the Loga Model 30 Th circular slide rule (see Fig. 1).
The circular slide rule has the following characteristics: 1. As the circumference is furnished with endless gradu- ations, the answer can never be off scale. 2. The circumference of the sliding disc is 3 times longer than the diameter of the disc.
