ST 03.1 – Continuous Beams

The objective of this equipment consists of the study of the deformation in the plane, of continuous beams under the action of loads.

Description

The equipment includes a clamping end and articulated sliding supports with dynamometer.

The deformation is measured by means of 3 dial gauges that can be placed in any point of the beam. These deformations are the answer of the system to the different applied loads.

The placing of the structure under load is obtained through 2 load systems with weights, whose maximum load is 12 kg, having weights of different masses, from 0.5 to 2.5 kg.

The equipment is provided with 2 beams of different sections, 20x5mm and 20x3mm.

Learning Objectives
  • Study of the deformation of a continuous beam.
  • Study of supports:
    • Clamping
    • Articulated sliding support
  • Comparison between calculated and measured displacements.
  • Application of the superposition principle.
