Elastic line of a beam (SE110.14)

Elastic line of a beam (SE110.14)

Beams of different materials: steel, brass and aluminium

CodeSE110.14

Description:

  • Beams are important design elements in mechanical engineering and building construction that can deform under load.
  • Beams are subjected to load transversely in the axial direction, which leads to deflection.
  • In linear–elastic material behaviour, the bending line, also known as elastic line, is used to determine the deflection of beams.
  • Deflection can be determined at any point on the beam using the influence coefficients and Maxwell–Betti’s commutative theory.
  • The SE 110.14unit is used to determine the deformation of a bending beam.
  • To do this, a beam is studied under varying loads, different support conditions and static indeterminacy.
  • The elastic line is determined by calculation and verified by experiment.
  • The experimental setup includes three beams made of different materials.
  • Two pinned supports and one fixed support with clamp are available.
  • The dial gauges record the resulting deformation of the beam.
  • The parts of the experiment are clearly laid out and securely housed in a storage system.
  • The entire experimental setup is constructed in the SE 112mounting frame.
