what is beams in engineering mechanics?

beam is a structural element that primarily resists loads applied laterally to the beam's axis. Its mode of deflection is primarily bybending. The loads applied to the beam result in reaction forces at the beam's support points. The total effect of all the forces acting on the beam is to produce shear forces andbending moments within the beam, that in turn induce internal stresses, strains and deflections of the beam.

The Beam
The term beam has a very specific meaning in engineering mechanics: it is a component
that is designed to support transverse loads, that is, loads that act perpendicular to the
longitudinal axis of the beam, The beam supports the load by bending only.
Other mechanisms, for example twisting of the beam, are not allowed for in this theory. The Elementary Beam Theory
In this section, problems involving long and slender beams are addressed.
