Behaviour of Column Struts Apparatus Manufacturer,Supplier and Exporter in India
Product Code : EL-SML-10071
Jlab Export is a leading Behaviour of Column Struts Apparatus Manufacturer,and suppliers in India
Behaviour of Column Struts Apparatus (code EL-SML-10071) is a buckling demonstration set of four spring steel columns mounted along a vertical wooden board, each held with a different pair of end conditions. Loading them shows how end fixity changes the load at which a slender strut bows sideways. JLab builds the board, the four struts and their stand in Ambala, India.

Euler Loads for the Four End Conditions
Euler’s formula gives the crippling load of a slender strut as P = π²EI / Le², where Le is the effective length. For a column of length L, Le = L with both ends pinned, L/2 with both ends fixed, L/√2 with one end fixed and the other pinned, and 2L with one end fixed and the other free. For columns of equal length and section this ranks the loads 4 : 2 : 1 : 1/4 for fixed–fixed, fixed–pinned, pinned–pinned and fixed–free.
Running the Comparison
Each strut is loaded with the weights until it bows, and the load is noted. Plotting the four observed loads against 1/Le² tests Euler’s prediction, while the buckled shapes show the half-waves and points of contraflexure that each pair of end conditions produces.
