Engineering Mechanics: Statics Theory | Radius of Gyration

[@emilioferrer1]

I remember when I was taking the mechanics of materials course, and this concept never made sense to me, now 3 years later I finally get to understand it, thanks!

Only remenber: Ix=r^2*A....is simple.

@@josealvarezperez111 it's always more simple to remember a formula than a concept, however, if you stay with the first one you should be called a technician, but if you choose the concepts side, you'll be an engineer, always remember, a technician knows how to do thing, but the engineer knows hoy to know.

@@emilioferrer1 What you say is true. Only sometimes the physical concept is implicit in the mathematical definition, as is the case of the definition of the radius of gyration with respect to the x axis:
Ix=rgx2*A=area integral of y2 dA. Precisely, later you can introduce the concept of mechanical slenderness as: landa=Effective light/rgx.
Another example occurs with the definition of the Mohr integral and Vereshagin's procedure for its resolution.
