Determine the minimum buckling force theoretically and experimentally to a rod that is supported in four different ways. Compare the results obtained with each other. Also draw theoretical buckling images and compare them to the buckling seen in the video.
Answer: Theoretical and experimental buckling forces are approximately equal.
