Ideal Column with Pin Supports Learning Goal: To use the formula for the critical load, i.e., the Euler buckling load, for pin-supported columns to calculate various parameters of columns. Ideally, a column that is perfectly straight and has an axial load applied exactly at the centroid of its cross section will not yield until the internal normal stress reaches the yield stress of the material. Real-world columns, however, are subject to small asymmetries, whether due to irregularities of shape or...

Derive the relation of the critical load of a long column pinned at both ends as shown where E, I, and L are Young’s modulus, moment of Inertia and the length of the column respectively.
The leg in (a) acts as a column which can be modeled as in (b)
Critical Buckling Load--Spring Connection The leg in (a) acts as a column which can be modeled as in (b), where the spring connection at the knee has stiffness k (torque/rad). Assuming the bones to be rigid, determine the critical buckling load. The critical load of a spring connection is: is a larger value than the pre-load state assumed to be a small angle approximation before buckling occurs found through the analysis of the FBD all of the above
