Description

Trusses are bar structures in which the bars are only subject to compressive or tensile stress, but not bending.Contains various smart, communication-enabled bars, equipped with electronic modules for data acquisition and measured value display. The experimental arrangement is set up in the mounting frame. The stainless steel mounting frame provides direct and wireless data transmission and power supply for the smart components.

The bars are hinge-connected to node disks and are only subjected to compression or tension. The click system ensures the bars easily snap into place in the node disks. Since no torques are transmitted in the node disks, they are considered frictionless. The trusses can therefore be regarded as ideal trusses.

Accessories such as supports, vertical load, load unit and additional bars are available for setup and for free experimentation. It is possible to create bridge connections, trusses across corners, larger trusses and indeterminate trusses. In experiments, all forces of the plane truss (bars, supports, loads) are measured and displayed both directly on the smart components and in the software as a measured value and as a colour. The calculated displacement can be demonstrated and amplified in the software. With the distance measurement accessory, the displacement can be measured and compared at any points.
