The apparatus consists of four panels, each measuring 40 cm horizontally and 30 cm vertically, from a PRATT steel truss. Each panel point can be subjected to load. To achieve noticeable member deformation, detachable springs should be included with all tension members. The diagonal members' directions can be altered. Equipment can be used to visually depict the types of forces arranged in different Truss components. A supporting stand and a set of weights should be included with the apparatus that is to be provided.

Experimental Capabilities:  Apparatus is supplied complete with a supporting stand and a set of weights
