The laboratory stand is designed for carrying out the demonstrational experiments during studying “Strength of materials” of technical mechanics course at higher technical educational institutions. It allows to determine critical load at loss of steadiness of central compressed flexible rod under various buckling loads with dependence on the type of fixing of the rod ends.
Structurally, the stand is made in the form of a prefabricated base on which there are two brackets supporting a rod of great flexibility. A screw is installed on the upper bracket to create the deformation of the rod with great flexibility. A weight sensor is installed in the lower bracket to measure the reaction force of the rod with great flexibility. Screws are installed on the brackets, with which you can change the way the rod is fixed with great flexibility.
To determine the magnitude of the deflection of a rod of great flexibility, an indicator head on a tripod is designed.
To display the readings of the weight sensor, use the measuring device NTC-13.01.10 “Digital strain gauge strain gauge”.
