SV303 – Deflection of Beams and Cantilevers


SV303 – Deflection of Beams and Cantilevers

The experiment deflection of beams and cantilevers allows the experimental investigation of the deflection of beams of different section sizes under different loads and types of support.

This experiment has the following properties:

  • Assembly of multiple different beam experiments via 2 adjustable supports, point load weight hangers and UDL weight sleeves
  • 3 different beam specimens of different section sizes and material


The beam specimens are made from either aluminium or stainless steel and are 20mm wide with either a thickness of 3 or 5mm.

The supports can be used in a fixed configuration where a clamping plate is used to hold the beam in place, simulating a fixed support.

By removing the clamping plate, the support can be used to simulate a simple support.

Loads can be applied to the beam through either two point load hangers or a uniformly distributed load (UDL) sleeve in combination with the two 500g slotted weight hangers. The point load hangers can be moved along the length of the beam allowing many different loading conditions to be explored.

The slotted weights supplied with the weight hangers can be used inside the UDL sleeve to simulate a UDL load applied to the beam.

The UDL sleeve has a central access point allowing the beam deflection to be accurately measured.
