Critical condition of Struts Apparatus

A piece of material in compression is called a strut. If it is short and stubby it will fail by compressive stress, but if it is slender the failure mode is that of buckling. The load at which the strut buckles depends on the way in which the ends are restrained. Built-in ends resist buckling more than ends which are free to move. Critical condition of Struts Apparatus apparatus shows how the buckling mechanism occurs, and the influence of the end restraint.

Critical condition of Struts Apparatus apparatus comprises a sheet metal frame which supports four slender spring steel struts having loading platforms at their top ends.

Experimental Capablities of Critical condition of Struts Apparatus

1. To observe the behaviour of four struts of the same length but with different end constraints when subjected to buckling loads.
2. To compare the result with theoretical predictions, such as Euler's formula.

Specification Of Critical condition of Struts Apparatus

1. Bench mounted apparatus.
2. Self contained unit. Demonstrates the critical buckling load for the four classical Euler conditions.
3. Both ends pinned
4. Open end pinned the other fixed
5. Both ends fixed
6. Base fixed, top free
7. Constructed of spring steel.
8. Allows struts to be buckled simultaneously
