Buckling Behavior of Bars Model MT 023

In technical mechanics, loss of stability is known as buckling. Under the effects of compressive forces, and
under increasing load, the axis of the bar deflects laterally until it suddenly and violently fails (collapses), even
before the fracture point is reached. The stresses in the bar often remain within the elastic range during this
process.
Sci-tech Buckling Behavior of Bars Model MT 023 investigates the buckling behavior of bars under various
influences. All relevant buckling problems are demonstrated by way of experimentation.
