Beam Deflection Explained | Formulas & Calculations | Modulus of Elasticity

When loading a beam, that beam will deflect based on a variety of factors which affect the stiffness of the beam. Correctly accounting for beam material, geometry, load placement and support structure are critical in solving for the correct deflection of a loaded member.

In this video we take a look at some of the beam loading configurations and the associated formulas which you will encounter in calculating beam deflection. We also take a look at Area Moment of Inertia and how it relates to the deflection of a loaded beam.

This video does not go into the deep detail that would be necessary in a higher level college course, however it does address the basic principles that would be found in an introductory college engineering course or even a high school engineering course such as Project Lead the Way Principles of Engineering.
