Determining of Maximum Stress in Circular and Circular Hollow Rod by Measurement of Strains

Abstract

The contribution deals with determining of stress from measured values of strains. Gauge strains, which were linked in half-bridge, and the universal measurement system QuantumX MX840 were used to experimentally obtain the strains. Rods with circular section and hollow circular section serve as tests samples. Students within the educational process will have the opportunity to acquaint with the universal measuring system and see the interconnectedness of theory and practical application.
