- Derivation of the formula for the calculation, among other things, of bending stresses
Hi,
A well-known part of the formula for calculating the deflection stress is ##I_z=\int \int r^2 dA##
Usually a moment of inertia is something related to how difficult is to move an object. In this case is understandable but i don't understand the meaning of the double integral.
Using ##r^4## wouldn't be the same?
