Hi, everyone, my friend asks me whether it is possible to: construct a extremely slender hollow column of 100 m long and less than 1 m* 1 m in cross-section dimension, which can withstand 10 ton compression force from the two ends without buckling/failure. The material is not fixed.

With such a large length-to-diameter (hollow section) ratio, intuitively, I think it is impossible to withstand the compression with such a slender column.But I am not very sure.

Hi, everyone:

A rectangular plate, simply supported at four edges, subjected to a partial load- a uniformly distributed pressure over a round area at the plate center. What is the analytical solution for the plate deflection?
