Structures - Deflection of Beams

This video demonstrates the Matrix Deflection of Beams experiment operating in manual mode, allowing students to perform hands-on structural engineering investigations while following the included curriculum workbook. As the second video in the Structures series, it highlights how the same equipment can be used without data acquisition, helping learners develop practical measurement, observation, and analytical skills.

Students assemble the apparatus, install different beam materials and support configurations, and measure beam deflection using a precision dial gauge. By applying incremental loads and recording measurements, they investigate how support conditions and material properties influence structural behavior. The resulting data can then be plotted and analyzed to compare theoretical calculations with experimental results, reinforcing key concepts in mechanics of materials and structural engineering.

What You'll Learn

• How to set up the Deflection of Beams experiment in manual mode
• The differences between fixed supports and cantilever support arrangements
• How beam material and support configuration affect deflection
• Using precision measuring equipment to record beam displacement
• Applying incremental loads and collecting experimental data
• Converting measurements into SI units for engineering calculations
• Plotting deflection versus load graphs and calculating gradients
• Comparing experimental results with structural engineering theory

Why Manual Mode Matters

Manual operation encourages students to take ownership of the experimental process by setting up the apparatus, collecting measurements, recording observations, and interpreting results independently. This approach strengthens practical laboratory skills while reinforcing the engineering principles behind beam deflection, structural supports, and material behavior.
