Abstract
This article presents the results of work carried out by students belonging to the Transport Structures research group at the Mukhamedzhan Tynyshpaev University ALT. Under the guidance of I. S. Bondar, the students built a lever loading test bench in the laboratory. A metal I-beam was used as the test specimen, to which strain gauges were attached in the middle of the span using cyanoacrylate adhesive in a half-bridge connection. The metal beam was loaded with weights ranging from 2 to 5 kg, which were hung on the lever system. The TENZO measuring complex was used to process and read the readings and strain gauges, allowing real-time relative deformations to be obtained for each strain gauge. The TENZO program automatically plots graphs of relative deformations and stresses. Next, students use Microsoft Excel to plot a graph of the stress state of the beam span structure model. The use of a strain gauge software and hardware system in the educational process helps students and master's students in engineering specialties to conduct research related to the strength of structural materials in laboratory conditions that are safe for students.
