The MST11 ultra static plane truss internal force and deformation testing experimental device is a specially designed experimental equipment for structural mechanics teaching. This device is mainly used to measure the key mechanical response of statically indeterminate planar trusses under vertical loads, including the internal force distribution of each member and the overall displacement deformation of the truss. Through experiments, students can systematically compare and verify the measured internal force data with the theoretical values calculated using the force method, thereby intuitively and deeply understanding the basic principles and calculation process ofusingtheforcemethodtosolvestaticallyindeterminatestructures.Thisnotonlyprovidesasolidexperimentalbasisforabstracttheoreticalcalculations, but also effectively enhances students' ability to analyze complex structuralproblems and solve practical engineering problems.

Experimental feature
1.Apply different loads and positions to truss models with the same geometric parameters, and record the internal forces and overall displacement of each member
2.Based on experimental data (axial force of members, reaction force of supports, node displacement), theoretical calculations are performed using the force method to verify the consistency between experimental results and theoretical values
3.Review the calculation ideas of node method and section method for statically indeterminate truss structures, and strengthen the application ability of force method for selecting advantageous and redundant constraints to simplify calculations in statically indeterminate truss structures
4.By analyzing errors such as node friction and material nonlinearity, we can understand the limitations of the ideal truss assumption and provide experimental support for the subsequent learning of approximate solutions (force method, displacement method) for statically indeterminate structures such as continuous beams and arch structures
