However, I found that the stress of the load doesn&#8217;t behave as I anticipated, I found that the axial stress transmits through the column as wave, here are some photos explain what I mean:<\/p>\n<p>&nbsp;<\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/08\/22-08-2023-1692716552-download (1).png\" alt=\"\"><\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/08\/22-08-2023-1692716567-download (2).png\" alt=\"\"><\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/08\/22-08-2023-1692716583-download (3).png\" alt=\"\"><\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/08\/22-08-2023-1692716608-download (4).png\" alt=\"\"><\/p>\n<p>What I was trying to make is, the charge when the column is fully stressed.
