What is the Area Moment of Inertia?

great video! please make a course series like this on FEA too!

that was super helpful thank you very much

Thanks for the video--very helpful. As I think through this equation, I am struck by the fact that the moment of intertia is not impacted by the material mass or properties. For some reason, I would have thought that intuitively the higher modulus of elasticity for metal would compound relative to wood. E.g. a metal and wooden bar of the same dimension will have the same moment of intertia (all else being equal). When I combine that with a beam deflection formula for a simply supported beam { D = [(W * L^3) / (48*E*I)] }, it means a percentage increase in the size of both material types will have an equal percentage impact on the beam deflection. Bedankt!

Excellent!

Awesome video

Great but the question is how F=EAi(∆L) = N.m which it is just N
