History of Science and Engineering Annotation << Back HISTORICAL SKETCH OF AGRICULTURAL INSTRUMENTS’ DYNAMOMETRY V.I. Myalenko Historical stages of measurement technology developing, especially dynamometers, during test of agricultural instrument are represented in the work. In the context of developing of dynamometers as measurement equipment, there is demonstrated historical requirement in development of new highly productive agricultural instruments. Indeed, tendency of developing technologies of domestic plants cultivation are required more accurate methods of analysis in any time period, during making of new equipment for agriculture. In conclusion was highlighted level of modern measurement basis during tests of agricultural instruments. Keywords: dynamometer, force and pair of forces, resistive strain sensor of resistance, Wheatstone bridge. DOI: 10.25791/intstg.07.2019.778 Contacts: E-mail: library82@ksai.ru Pp. 67-72.
