DEFLECTION : In engineering,deflection  is the displacement of the member from original position under the influence of external forces. In beams generally the external forces causing the deflection are transverse loads. But in general we cannot see the deflection in our structures, as the beams are designed to resist loading and deflection even if there is deflection it will be of small magnitude which we can't see with our naked eyes. DEFORMATION : On earth every thing has a form (i.e, its shape and size ), when these things are subjected to external factors they undergo some permanent changes in their shape, and size and the changes are known as  Deformations. What is difference between Deflection and Deformation? Generally, there is a misconception in students that  Deflection and Deformation are basically same but that is not totally true.Deflection is a type of deformation but with non permanent changes in form. There are many types of deformation such as extension,shrinking
