Beam:
Structural elements capable of withstanding load primarily by resisting bending are known as structural beams. Bending moment is the bending force induced into the material of the beam as a result of external loads, own weight, span and external reactions to these loads.
Reinforcement Steel Bar:
Reinforcing steel bars are used to help concrete withstand tension forces. Concrete is sufficiently strong to compression forces by nature, but tension forces can crack it.
