It is necessary to check that relatively long compression springs are not are
risk of buckling. If buckling is a problem it is necessary to incorporate
some method of guiding the spring by placing it in a hole or on a suitable rod.
Just as a column will buckle when the load becomes too large a long compression spring may buckle when the deflection exceeds a certain value. The critical deflection is given by the following equation.

Absolute stability occurs when C'2 /λeff2 is greater than unity. The condition for absolute stability is therefore.

The equation for the lowest natural frequency of a compression spring located between two flat plates is..
Forcing frequencies near the above lowest natural frequency and at whole multiples (2,4,6...) of this frequency.
