Paperback. Condición: New. Print on Demand. This book provides guidance on the principles and practice of leveling for various engineering and construction projects. The author begins by defining what leveling is and explaining its significance in determining the difference in distances from the center of the earth, known as "true level," versus the level measured from a point on earth's surface, called "apparent level." The author then provides formulas for correcting for the effects of earth's curvature and refraction. Along with the principles of leveling, the author also details the necessary instruments, including the Y level, Troughton's improved level, and the Dumpy level, as well as the accessories such as leveling staves and measuring chains. The author provides thorough instructions for using these instruments effectively, including adjusting for observation and eliminating parallax. With clear explanations and diagrams, this book imparts the knowledge and skills necessary for accurate leveling operations in various fields like railway engineering and road construction, which are crucial for successful project execution and ensuring the stability of structures.
