Four identical pin-pin ended solid concrete cylindrical columns that are L=10m tall need to be able to withstand 6.8×108N of force before Euler buckling. What should be the diameter, d, in meters, of each column if the force is uniformly distributed? The Young’s modulus, E, for concrete is 17GPa, and I=πr44. Assume n=1.
