MVV Unsymmetrical Cantilever Unit
The Unsymmetrical Cantilever Unit, "MVV", is designed to demonstrate the unsymmetrical bending of beams.
The system consists of a vertical cantilever rigidly clamped at its lower end to the main column which is attached to a rigid structure. Beams of different sections may be used.
A loading head, located at the upper end of the column, can rotate freely around the vertical axis of the beam at 15º intervals. A horizontal load may be applied to the free end of the beam by means of a cord attached to the beam and passing over a pulley mounted on the rotating head.
The Δu and Δv deflections of the beam are measured by means of two dial gauges mounted perpendicularly to each other on the head. To compensate any lateral deflection of the beam, the line of action of the applied load can be adjusted by lateral adjustment of the load pulley.
Two steel beams are supplied, one with rectangular section and the other one with L shape section.
Exercises and guided practices
GUIDED PRACTICAL EXERCISES INCLUDED IN THE MANUAL
- Determining the deflection of the beam depending on theintensity of the force applied.
- Determining the deflection of the beam depending on thedirection of the force applied.
- Determining the Δu and Δv deflections at free ends of cantilevers.
- Studying the deflections at two planes, for several sections.
- Determining deflections for different angles of force applied.
- Studying the rigidity variation.
- Determining the position of the torsion centre of the beam (Itrequires the optional accessory MVV/1).
