Product Details

Technical Description 
The set is intended for use with the universal test frame SE 111 and demonstrates simple stability problems. The core of the set is a two-part test bar with a central joint at which the buckling load can be determined under varying boundary conditions. The elastic low-friction joint is represented by a torsion spring fitted between the two parts of the test piece. Loading is performed continuously using a lever with a set of weights. An exact scale on the lever permits the load to be determined with precision. Varying clamping is possible by means a steel spiral spring of variable length on the lower bearing. A further set of weights with a cord is used to generate lateral forces.

Learning Objectives / Experiments

- Determination of the buckling load at varying boundary conditions
  + elastic joint
  + elastic clamping
- Influence of additional shear forces
- Influence of predeformation

* Continuous adjustment of the load on the test bar1
* Varying amount of clamping by means of spiral spring
