This Pin-Jointed Truss Experiment Unit enables users to study force distribution and deflection in four common truss frameworks. It features interchangeable square-section members for easy configuration and strain gauges on key members for accurate force measurement. A strain gauge amplifier and load cell allow precise monitoring of stress responses under different loading conditions. Fully integrated with EDAQ software, the system supports real-time data collection and graphical analysis. Students can explore concepts like Bow’s Notation, force analysis, and strain-energy-based deflection calculations. The package includes a strain gauge amplifier, supports, a digital indicator, truss members, joint bosses, a load cell, and storage trays.
Specification
• Works with EDAQ software for real-time data acquisition and analysis.
• Users can analyze forces and deflections in four popular pin-jointed trusses:
• The Warren truss.
• The Roof truss (Howe/Pratt truss).
• Simple cantilever truss.
• Advanced cantilever truss.
• Users apply loads to the trusses and measure resulting forces and deflections.
• Strain gauges connect to a strain gauge amplifier, which, along with the load cell, links to the USB interface hub for digital display and data acquisition.
