The bench top unit is used for studying buckling on struts under various end conditions. A type of failure that is sometimes overlooked for a body subject to compressive load is that due to instability, called buckling.
The unit Column Buckling Apparatus consists of two vertical columns where load is applied by a screw via a sliding guide in a ball bushing. Pivot support is a wedge on a V-notch and built-in support is a cylinder in a socket. Load on the strut is measured by a load cell and deflection is measured by a dial gauge. Side loading is by a weight hanger and weights. Height of loading beam is Adjustable to accommodate different strut lengths.
