MFV Beam Deflection Unit



The Beam Deflection Unit, "MFV", enables the student to demonstrate the fundamentals of bending by studying the deflection produced in metallic flat bars, which simulate the behavior of beams, subjected to different loads.

See general description


General Description

The Beam Deflection Unit, "MFV" has been designed to enable the students to observe and study the following phenomena in simply supported beams and cantilever beams:

  • Relation between the deflections and the applied loads.
  • Effect of the length and the cross section on the beam behaviour. Ex: deflection load ratio.

The "MFV" unit consists of an aluminum and stainless steel structure to carry out experiment with metal beams up to a length of 1 m. Three beams with different cross section are supplied.

The structure makes it easy to study cantilevers holding the beam by one end, or beams simply supported on two points.

The "MFV" unit gives us the possibility of modifying the position of the supporting and holding points.

It has a graduated ruler fixed on the structure that allows to obtain measures easily in different points of the beam.

The weights will be hung from hooks, in order to apply the load on any point in the beam.
