Beam Theory - Wondering How To Calculate The Beam Strength

A beam is a structural element that is capable of withstanding load primarily by resisting bending. The bending force induced into the material of the beam as a result of the external loads, own weight and external reactions to these loads is called a bending moment.

A loaded beam deflects by an amount that depends on several factors including:

  • the magnitude and type of loading
  • the span of the beam
  • the material properties of the beam (Modulus of Elasticity)
  • the properties of the shape of the beam (Moment of Inertia)
  • the beam type (simple, cantilever, overhanging, continuous)

 

 
To many people, this topic they would have come across at the college levels. But for sure these are essential fundamentals to be known for Engineers who are at building products, construction etc., I will try to cover more topics on Strength of Materials.
