Hi all
I was hoping someone could help explain the difference between Young's Modulus and Second Moment of Area.
I know that Young's modulus is a measure of how elastic a material is and is calculated by Stress/Strain.
I know that the Second Moment of Area can be defined as a objects resistance to bending.
But if I had a material that had a high Young's Modulus meaning that it was less elastic in other words more stiff then isn't that the same thing as the second moment of area?
Can anyone see where I am coming from?
I know the two are related but to me they seem like they are describing the same thing?
The only difference I can see is that Youngs Modulus describes stiffness in terms of elongation/compressions whereas the second moment of area describes bending/deflecting.
Can someone explain or define the concepts if I have it wrong?
Thank you.
