A Treatise on Mathematical Instruments: Including Most of the Instruments Employed in Drawing (Classic Reprint) - Softcover

Inhaltsangabe

A practical history of drawing and surveying tools that equips you to understand, use, and evaluate classic instruments. This long-standing reference surveys mathematical drawing instruments from compasses and rulers to goniometers and levels. It explains construction, adjustment, and everyday use, with careful notes on accuracy and application for draftsmen, surveyors, and instrument makers.

Richly described are the major tools used in drawing and measurement, including the design and functioning of compasses, hair-compasses, and precision points. The work also covers proportional and bow compasses, plotting scales, and the pantograph, as well as how to copy, reduce, or enlarge drawings with accuracy. Theory and practice are blended to help the reader master practical mathematics in real projects.

• Clear explanations of how to set and use drawing compasses, pen points, and hair springs for fine accuracy


• Guidance on proportional, scaling, and plotting instruments for enlarging or reducing drawings


• Insights into optical and surveying instruments, including levels and the principles of collimation


• Practical notes for students and professionals on selecting, adjusting, and maintaining classic instruments

Ideal for readers of practical mathematics, drafting, surveying, and the history of measurement tools.
