This structure illustrates and proves the basic theory of bending moments in a beam.

The experiment hardware is a simply supported beam ‘cut’ by a pivot. Students apply loads at set positions using hangers holding various masses. To stop the beam collapsing, a moment arm bridges the ‘cut’ onto a load cell, thus reacting to (and measuring) the bending moment force.

Learning Outcomes

• Bending moment variation at the point of loading
• Variation of bending moment away from the point of loading
• Examination of various other loading cases, including loads traversing the beam
