Column buckling machine
WebColumn strength is the ability of the lift shaft to hold compressive loads without buckling. With longer screw lengths, column strength can be substantially lower than nominal jack capacity. If the lift shaft is in tension only, the screw jack travel is limited by the available screw material or by the critical speed of the screw.

WebColumn Buckling and Slenderness Ratio. In this lab, three different lengths of plastic I-beams are tested under compression to investigate their method of failure. The way in which a member fails (buckling or not) is determined by its Slenderness Ratio, which is calculated for each beam. This lab also covers the Radius of Gyration and the Area ...
