Problem

A slender steel push-rod has a solid circular cross-section of diameter

d = 12\,\mathrm{mm}

and length

L = 0.9\,\mathrm{m}

, with

E = 200\,\mathrm{GPa}

. ((a)) Find its Euler buckling load if both ends are pinned. ((b)) Find its Euler buckling load if both ends are clamped, and express the result as a multiple of the pinned value.
