The MST08 two hinge arch constraint force testing experimental device is an experimental module designed specifically for structural mechanics teaching. This device is optimized and designed based on the application requirements of civil engineering and mechanical engineering, consisting of two support supports and a symmetrical bridge arch structure rigidly connected. It can accurately simulate the stress state of two hinged arches under vertical loads (concentrated or uniformly distributed), measure and display the horizontal thrust and support reaction generated by the structure in real time, and intuitively verify the stress difference between the arch structure and the corresponding simply supported beam. It is an ideal teaching tool for understanding the mechanical characteristics of staticallyindeterminate thrust structures.

Experimental feature
1.Horizontal thrust test: Verify the relationship between thrust and arch height, span, and material stiffness in statically indeterminate structures, and compare the stress differences between statically indeterminate and statically indeterminate arch structures
2.Mobile load analysis: By using weights to move and load at different positions on the arch, the curve of horizontal reaction force changing with load position is tested and plotted. The distribution law of internal forces (bending moment, axial force) in the section is analyzed using the principle of force method
3.Uniformly distributed load simulation: Equipped with uniformly distributed load rods of different lengths (long rods/short rods), it can simulate the uniformly distributed forces under actual working conditions such as bridges, measure and compare the measured thrust and force method theoretical calculation values
4.Verification of hyperstatic characteristics: Integrated visual teaching unit, real-time presentation of experimental data and dynamic curves, supporting intuitive comparison between theoretical calculation values and measured data, assisting in understanding the basic system of force method and the concept of solving for excess unknown forces
