Caliper Abuse for Beginners a Guide to Quick and Accurate Layout Using Digital Calipers
Caliper Abuse for Beginners A Guide to Quick and Accurate Layout Using Digital Calipers charles z guan productions 21 Mar 2010 In your 2.007 kit, you have been provided with a set of 6” (150mm) digital calipers. You should use these not only for measuring and ascertaining dimensions of parts, but for accurate positioning of holes and other features when manually fabricating a part. Marking out feature positions and part dimensions using a standard ruler is often the first choice for students unfamiliar with engineering tools. This method yields marginal results and usually results in parts which need filing, sanding, or other “one-off” fitting. This document is intended to exposit a fairly common but usually unspoken shortcut that balances time spent laying out a part for fabrication with reasonably accurate results. We will be using a 3 x 1” aluminum box extrusion as the example workpiece. Let's say that we wanted to drill a hole that is 0.975” above the bottom edge of this piece and 1.150” from the right edge. Neither dimension is a common fraction, nor a demarcation found on most rulers. How would we drill such a hole on the drill press? Here, I have set the caliper to 0.975”, after making sure it is properly zeroed. Use the knurled knob to physically lock the caliper to a reading. These calipers have a resolution of 0.0005”. However, this last digit is extremely uncertain. Treat your dimensions as if Calipers are magnetic and can they only have 3 digits attract dirt and grit. -
FIELD EXTENSIONS and the CLASSICAL COMPASS and STRAIGHT-EDGE CONSTRUCTIONS 1. Introduction to the Classical Geometric Problems 1
FIELD EXTENSIONS AND THE CLASSICAL COMPASS AND STRAIGHT-EDGE CONSTRUCTIONS WINSTON GAO Abstract. This paper will introduce the reader to field extensions at a rudi- mentary level and then pursue the subject further by looking to its applications in a discussion of some constructibility issues in the classical straight-edge and compass problems. Field extensions, especially their degrees are explored at an introductory level. Properties of minimal polynomials are discussed to this end. The paper ends with geometric problems and the construction of polygons which have their proofs in the roots of field theory. Contents 1. introduction to the classical geometric problems 1 2. fields, field extensions, and preliminaries 2 3. geometric problems 5 4. constructing regular polygons 8 Acknowledgments 9 References 9 1. Introduction to the Classical Geometric Problems One very important and interesting set of problems within classical Euclidean ge- ometry is the set of compass and straight-edge questions. Basically, these questions deal with what is and is not constructible with only an idealized ruler and compass. The ruler has no markings (hence technically a straight-edge) has infinite length, and zero width. The compass can be extended to infinite distance and is assumed to collapse when lifted from the paper (a restriction that we shall see is irrelevant). Given these, we then study the set of constructible elements. However, while it is interesting to note what kinds objects we can create, it is far less straight forward to show that certain objects are impossible to create with these tools. Three famous problems that we will investigate will be the squaring the circle, doubling the cube, and trisecting an angle. -

6. Determination of Height and Distance: Theodolite
Geography (H), UG, 2nd Sem CC-04-TH: Thematic Cartography 6. Determination of Height and Distance: Theodolite What is Theodolite? A Theodolite is a measuring instrument used to measure the horizontal and vertical angles are determined with great precision. Theodolite is more precise than magnetic compass. Magnetic compass measures the angle up to as accuracy of 30’. Anyhow a vernier theodolite measures the angles up to and accuracy of 10’’, 20”. It is of either transit or non- transit type. In Transit theodolites the telescope can rotate in a complete circle in the vertical plane while Non-transit theodolites are those in which the telescope can rotate only in a semicircle in the vertical plane. Types of Theodolite A Transit Theodolite Non transit Theodolite B Vernier Theodolite Micrometer Theodolite A I. Transit Theodolite: a theodolite is called transit theodolite when its telescope can be transited i.e. revolved through a complete revolution about its horizontal axis in the vertical plane. II. Non transit Theodolite: the telescope cannot be transited. They are inferior in utility and have now become obsolete. Kaberi Murmu B I. Vernier Theodolite: For reading the graduated circle if verniers are used, the theodolite is called a vernier theodolit. II. Whereas, if a micrometer is provided to read the graduated circle the same is called as a Micrometer Theodolite. Vernier type theodolites are commonly used. Uses of Theodolite Theodolite uses for many purposes, but mainly it is used for measuring angles, scaling points of constructional works. For example, to determine highway points, huge buildings’ escalating edges theodolites are used. -
Basic Drawing Equipment Worksheet
Drawing Equipment Technical drawings, graphic images and sketches can be created using a variety of instruments, ranging from traditional tools such as pencils, compasses, rulers and a variety of triangles as well as by computer. Drawing tools are used to make accurate and legible drawings and models. Whilst the computer can be used for most drawing and modeling requirements today, traditional drawing instruments such as those mentioned above are still important very important, particularly for freehand sketching and experimenting with shapes and lines. When drawing, sketching or attempting basic graphics work the pieces of equipment shown below are very useful and often essential. A protractor is used to measure angles. A typical protractor is a semi- circular piece of plastic with 180 degrees printed around its curve. This piece of equipment is not only used in graphics for constructing accurate drawings but is also used in subjects like Mathematics. Also available for graphics is a full circle protractor which can be used to accurately measure angles greater than 180 degrees. A Mechanical pencil (sometimes known as a clutch pencil or refillable pencil) are used in drawings such as Orthogonal or Isometric drawings as they provide a very constant line thickness. The pencils come in a number of line thicknesses with the more common being 0.35, 0.5, and 0.7. These pencils can be very expensive as are the refills. A compass (or pair of compasses) is a technical drawing instrument that can be used for drawing circles or arcs. As dividers, they can also be used as tools to measure distances, in particular on maps. -

Pottery Throwing Tools

That’s all changed today as many manufacturers make a wide selection of tools to fill most of the pottery throwing needs for ceramic artists. However, for the potter with special needs or who wants a special tool, making your own tools is both creative and fun— plus you get tools that may not be available anywhere else. How to Make and Use Bamboo Tools by Mel Malinowski There’s a nostalgia for making handmade tools and bamboo is one of the best materials for making long-lasting durable pottery throwing tools. The material is easy to shape and readily available. How to Make Ergonomic Pottery Throwing Sticks by David Ogle Pottery throwing sticks are a potters best friend when it comes to throwing tall, narrow or closed forms. Held in the hand, these versatile tools can reach places no hand could touch. And if you can’t find ones to buy that work for you, David Ogle shows you the step-by-step process for making your own. How to Use a Throwing Stick by Ivor Lewis Pottery throwing sticks are hand-held tools that are a potter’s best friend when it comes to throwing tall, narrow or closed forms. -

It never occurred to me that the modern compass is not the one that Euclid wrote about. In this document, I present the collapsing compass and other surprising geometric constructions. The mathematics used is no more advanced than secondary-school mathematics, but some of the proofs are rather intricate and demand a willingness to deal with complex constructions and long proofs. The chapters are ordered in ascending levels of difficult (according to my evaluation). The collapsing compass Euclid showed that every construction that can be done using a compass with fixed legs can be done using a collapsing compass, which is a compass that cannot maintain the distance between its legs.
