TQ's Redundant Truss teaching apparatus enables a range of laboratory, classroom and computer-based experiments for civil, mechanical and structural engineering students studying indeterminate framed structures.
Experiments include investigations into strains, stresses, forces and deflections in:
|
 |
a statically determinate framework |
|
|
a statically indeterminate framework |
 |
| To ensure it meets your teaching needs, TQ's Redundant Truss teaching apparatus is available in various hardware and software formats. Choose from: |
 |
Hardware only |
| Hardware with virtual (computer-simulated) experiments |
|
Hardware with automatic data acquisition and virtual experiments |
| Virtual experiments only, included in the Virtual Experimentation Pack (STRS) |

HARDWARE
TQ's Redundant Truss hardware includes two framework supports, one allowing pivoting and the other allowing pivoting and rolling. To perform experiments, students measure and compare the strains, stresses, forces and deflections of a determinate and then an indeterminate frame structure.
Each member has a strain bridge attached. Students use an electronic load cell to apply loads to the structure. A digital deflection indicator measures deflection, while a digital strain bridge measures member strains (thus forces).
The Redundant Truss hardware includes a lead to connect the load cell to a Digital Force Display (STR1a). It also includes an electronic load cell, digital deflection indicator, stainless steel members with strain gauges attached, a lecturer guide and a student guide.
Essential ancillaries:
To use the Redundant Truss hardware you will also need:
Structures Test Frame (STR1) and a
Digital Force Display (STR1a)
Recommended ancillaries:
Structures Virtual Experimentation Pack (STRS)
The Automatic Data Acquisition Unit (STR2000) will enable automatic data acquisition from the Redundant Truss hardware. As an additional benefit, the Redundant Truss virtual experiment is FREE!

VIRTUAL EXPERIMENTS
The Redundant Truss Virtual Experiments Software enables computer simulation of experiments working with or without the Structures teaching hardware. It expands the scope of experimentation beyond the limits of the hardware, allowing students to select the Young's modulus of the material. As well as simulating the extensive range of experiments possible with the Redundant Truss hardware module, the software also extends the principles illustrated by the Continuous and Indeterminate Beams (STR13) module to include internal redundancy.
For increased understanding, during experiments the software simultaneously displays the theoretical strains and forces in all the connected members using a highlighting system. Students can visualise, tabulate and graph data, reducing the time required for students to obtain, process and present results. This allows students to realistically, efficiently and conveniently investigate and compare the properties of a wide selection of redundant truss frameworks under varying applied loads.
The Virtual Experiments Software is available in a variety of multi-user and networked options, as well as single-user format.
