Difference between Stiffness (K) and Modulus of Elasticity (E)?
Stiffness (F=Kx) is the extent to which an object resists deformation in response to an applied force. Elastic Modulus (E=Stress/Strain) is a quantity that measures an object or substance's resistance ...

Should we use Hooke's Law (that linearly relates stresses to strains) if the stiffness of body is changing during deformation?
Assume I have a slender cantilever beam, fixed at one end and force applied on the other. Now, during the deformation, we know that the beam's stiffness is going to change and the force-displacement ...

Buckling in Columns
The following images are taken from Mechanics of Materials, Ferdinard Beer et al. 6th ed (2012)
Just wondering that why the effective length of the column is taken 0.7 L (highlighted in the sample ...
