Redundant Truss
Product Code : EL-NGSP-11387
Quick Answer: The Redundant Truss shows the analysis of statically determinate and indeterminate trusses, with strain gauges on every member to measure member forces. A thumbscrew engages or releases an extra redundant member.

Key Features
- Strain gauges on each truss member measure the forces due to the load
- Indicator measures the framework deflection
- Hand-operated load cell assembly applies and measures the load at the free end joint boss
- Two supports: one allows rotation only, the other rotation and translation
- Thumbscrew engages and disengages the extra redundant member
- Strain gauge amplifier and load cell connect to the Structures platform interface hub for computer display and data acquisition

About This Product
Students first load the truss without the redundant member, when it is stable and can be solved by static equilibrium alone. Engaging the extra member makes it statically indeterminate, so they compare member forces and deflections for both cases and check the results with methods such as strain energy. Enquiries from Yemen, Sudan, Japan, Mauritius, Tanzania and Angola for the Redundant Truss receive an export quotation.
Frequently Asked Questions
How is the redundant member added to the Redundant Truss?
A thumbscrew engages and disengages the extra redundant member, turning the frame from statically determinate to indeterminate.
How are member forces measured?
Strain gauges on each truss member measure the forces, through a strain gauge amplifier connected to the Structures platform interface hub.
