HST10 Bending Moment in a Beam

HST10 Bending Moment in a Beam

When a simply supported beam is loaded along its length two main forces occur internally; shear and bending. Bending can be seen visually but shear is not so easy. This experiment takes the internal forces from inside the unit to the outside so that the students can see clearly how the beam reacts.

Each beam is simply supported on vertical supports which can be positioned in a variety of positions along the beam lengths. At the ‘cut’ section, a bearing in one beam rests inside a radiused pocket of the other beam. This restricts any vertical movement between the two beams (hence removes any visible shear force), but does not restrict rotation between the two beams and hence bending is not restricted.

In their unloaded state the beams are levelled using the level indicator provided. Loads are applied to the beam using the load hangers and calibrated weights set. The force transducer connects to the HDA200 Interface (sold separately). 

A comprehensive instruction manual for lecturer and student, giving full details on apparatus assembly and operation as well as example results. All necessary assembly and operational tools are provided.
