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
