Product Overview

The Redundant Truss apparatus is a comprehensive educational system designed to explore both statically determinate and indeterminate truss structures. Integrated with the Structures platform for real-time data acquisition and analysis, this apparatus allows students and engineers to investigate internal member forces, structural deflections, and the comparative performance of various truss configurations under realistic loading conditions.

Learning Outcomes

• Strain Gauge Applications
  Learn to use strain gauges as precise measurement tools for capturing internal force and deformation in structural elements.

• Real-Time Force & Deflection Analysis
  Investigate the force distribution and deflection patterns in redundant and simple trusses under point and distributed loads.

• Classical Structural Analysis Methods
  Master the Method of Joints and Method of Sections to calculate internal forces in both determinate and indeterminate truss systems.

• Energy-Based Analysis
  Apply the strain-energy method for advanced structural analysis, particularly in evaluating complex or redundant frameworks.

• Comparative Study
  Explore the benefits and limitations of:

  • Statically Determinate Trusses – Simpler analysis, less redundancy.

  • Statically Indeterminate Trusses – Greater stability, load-sharing potential, and redundancy in structural performance.
