Redundant Truss Didactic Equipment Mechanical Training Equipment

I.Product Overview
As lightweight structures with high rigidity, trusses are used in the construction of halls, bridges, cranes, towers and masts. Trusses are steel structures in which the bars are subjected to compressive or tensile loads but do not bend.
The aim of the experiment is to measure the bar forces in a single plane truss subjected to a single external force. The bar ends of the experimental device are equipped with fixing holes for convenient fixing to the node disks. The range of different tie rod lengths offered allows the construction of two statically determined trusses.
The test bars are articulated, connected together via node disks and are subjected only to compressive or tensile stresses. No moments are transmitted in the nodes; they can be considered frictionless. Therefore, our trusses can be considered ideal trusses. The load application devices connected to the node disks generate external forces. All forces on the truss bars are recorded by strain gauge measurements. The display allows a direct indication of the forces to which the force measuring tie rods are subjected.

IV. Truss Introduction
A truss is a structure made of rods connected to each other at both ends with hinges. A truss is generally a plane or space structure composed of straight rods and consists of triangular units. The truss rods mainly bear axial tension or pressure, so that the strength of the material can be fully utilized. When the span is large, it can save materials, reduce deadweight and increase rigidity compared to solid beams.
The advantage of the truss is that the rods mainly bear tension or pressure, which can give full play to the role of the material, save materials and reduce the weight of the structure.
