WebStiffness is the resistance of an elastic body to deflection or deformation by an applied force - and can be expressed as. k = F / δ (1) where . k = stiffness (N/m, lb/in) F = applied force … WebArea Moment of Inertia. The second moment of area, more commonly known as the moment of inertia, I, of a cross section is an indication of a structural member's ability to resist bending. (Note 1) I x and I y are the moments of inertia about the x- and y- axes, respectively, and are calculated by: I x = ∫ y 2 dA. I y = ∫ x 2 dA.
