Bending Moments in a Beam
Product Code : EL-NGSP-11393
Quick Answer: The Bending Moments in a Beam experiment has a beam on a pinned support and a roller support, loaded through hangers along its length. A load cell at a cut at mid-span measures the bending moment caused by the load.
Last updated: October 2026
Key Features
- Hangers suspended along the beam for applying loads
- One pinned support (rotation only) and one roller support (translation)
- Load cell at the mid-span cut measures bending moment
- Central span with an overhanging end for positive and negative bending moments
- Support pointers read against the platform scale for positioning
- Uniformly distributed load (UDL) included for comparison with a single point load

About This Product
Students predict the bending moment at the cut for different load positions and compare it with the load cell reading. Moving a load along the beam lets them build the influence line and bending moment diagrams, and the overhang shows how moments change sign beyond a support. Schools, colleges and institutes in Sudan, Bahamas, South Sudan, Belgium and United States can order the Bending Moments in a Beam from Educational Instrument.
Frequently Asked Questions
Can negative bending moments be shown with the Bending Moments in a Beam experiment?
Yes. The beam has a central span with an overhanging end, so both positive and negative bending moments can be created.
Is a distributed load supplied?
Yes. A uniformly distributed load (UDL) is included for comparison with a single point load.
