Book excerpt: Agricultural and Horticultural Engineering: Principles, Models, Systems, and Techniques focuses on the developments in agriculture and horticulture, including the role of engineers in employing measures in the management of plants, animals, and machinery. The book first offers information on the process of surveying, including tape, compass, and aerial surveying, leveling, barometric leveling with the aneroid, plane tabling, and electronic distance measurement and electronic total. The text then takes a look at models of the environment, material properties, and the relationship between stress and strain. The publication examines workshop methods and hydraulics. Topics include soldering, electric arc welding, low temperature brazing, welding using oxygen-acetylene apparatus, hydrodynamics, and water supply requirements. The text also reviews electricity and electronics and power and thermal systems, as well as alternating voltage supplies, electrical motors, electrical safety, power and energy consumption, and the fundamental principles of electronics. The manuscript is a dependable reference for engineers and readers interested in agricultural and horticultural engineering.
