# MFLT Strut Buckling Unit

## INNOVATIVE SYSTEMS

The Strut Buckling Unit, "MFLT", has been designed by EDIBON for demonstrate the buckling of structures by compression, allowing to calculate the critical buckling load in function of different end fixation conditions.

See general description

## General Description

The Strut Buckling Unit "MFLT" allows the student to obtain experimentally the buckling critical load of slender struts subjected to compression.

The unit allows to study the buckling of pieces of different lengths, ranging from 300 mm. to 625 mm., to which different support conditions can be applied:

• Pin-joined end conditions.
• Rigidly fixed end conditions.
• One end pinned and the other fixed.

To carry out the practical exercises correctly , it is very important to apply the force with an only axial component. For that purpose, the MFLT unit has a differential screw placed at one end, which allows the system compression.

To measure the compression force exerted on the structure, there is a system composed of an elastic ring whose deformation is measured. The compression force will be directly proportional to the deformation registered in a dial gauge.

## Exercises and guided practices

### GUIDED PRACTICAL EXERCISES INCLUDED IN THE MANUAL

1. Study of deformation in beams.
