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 unit 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 overdetermination. The elastic
line is determined by calculation and verified by experiment.
