SD-3.12 Universal Strut Apparatus

The Universal Strut Apparatus has been developed to enable students to carry out a series of tests to determine the crippling load for struts of varying slenderness ratios and end fixing conditions.

Description

The Universal Strut Apparatus has been developed to enable students to carry out a series of tests to determine the crippling load for struts of varying slenderness ratios and end fixing conditions.

The apparatus has been designed to accommodate struts of suitable lengths within the range 400 to 800 mm. The struts are rectangular in cross section, thus ensuring that the deflection occurs in a predetermined plane.

Reversible hardened load blocks are provided so that the struts can be tested under the following conditions:

  1. Both ends pinned
  2. Both ends fixed
  3. One end pinned, one end fixed

The load is applied to the strut by means of a spring balance and a loading beam. The beam pivots on a nut which can be adjusted vertically so that the beam can be maintained in the horizontal position during loading, thus ensuring that a true axial load can be supplied throughout the test.

A light lateral load is applied to the strut to ensure the direction of deflection, the magnitude of which can then be measured by means of a dial indicator.

One set of struts for each end condition (see conditions 1,2,3 above) is supplied with the apparatus. Complete with masses.

Extra
A set of load blocks, bushes and specimens are available to allow experiments to be conducted on round specimens.
