Speed up structural calculations with parallel tables of logarithms and squares.
This edition brings together log functions, squares, and angle data designed for engineers, architects, and draftsmen. It helps you find hypotenuses, bevels, and multiple trig-related values in one streamlined process.
In clear, practical terms, the book shows how to combine tables to solve right-triangle data quickly, read bevels from angles, and cross-check results as you work. It also includes real examples and guidance on using these tables for everyday drafting tasks.
- Learn how to compute diagonals, slopes, and log values without flipping between multiple tables.
- Understand how to derive bevels from known sides or angles and vice versa.
- See practical steps and checks that improve accuracy and speed on the job.
- Explore examples that demonstrate the method and its limits for precise work.
Ideal for readers who do hands-on drafting and need reliable, quick-reference tools for geometry, measurement, and log/square calculations in feet and inches.
