Redundant Truss Apparatus Model MT 078
Redundant Truss Apparatus Model MT 078
Sci-tech Redundant Truss Apparatus Model MT 078 fits onto a Structures Test Frame. Two
supports hold the top and base of one side of a structure. The top support allows pivoting, the base support allows pivoting and rolling. Initially, one of the members is missing from the structure, making it determinate. To make the structure indeterminate, students refit the missing member.
Students manually apply a load to one end of the determinate framework using a screw-thread and electronic load cell. The load cell connects to a Digital Force Display which shows the applied load.
Each member of the structure has strain gauges attached. These each connect to a digital strain bridge which shows the member strains. Students use the strains to help them calculate the forces in the structure. A digital deflection indicator measures displacement in the structure.

Students note applied load, strains and deflection in a determinate framework. They then repeat the experiment with the frame made indeterminate and analyze and compare their results.
