It is used both for quantitative measurements and for demonstrating complex stress states. Photoelasticity is a proven method of analysing and recording mechanical stresses and strains in components. The components used are models made of a transparent, photoelastically sensitive plastic, which becomes optically birefringent under mechanical load.
Features:
Generate stress patterns with linear or circular polarised light
Monochromatic or white light.
Tensile Modulus Of Elasticity is to be used with Universal Structural Frame. The rod is mounted between two gripping heads and a load of upto 3 kN is applied by means of a screw with turning wheel. Elongation of the gauge length is measured by two dial indicators. Tensile Modulus Of Elasticity equipment is used for studying the modulus of elasticity of materials in the form of rods. The load is measured by a force indicator.

Beams are important design elements in mechanical engineering and building construction that can deform under load. In linearelastic material behaviour, the bending line, also known as elastic line, is used to determine the deflection of beams. Deflection can be determined at any point on the beam using the influence coefficients and commutative theory. Beams are subjected to load transversely in the axial direction, which leads to deflection.
Features:
Beams of different materials: steel, brass and aluminium.
Learning Objectives And Experiments:
Elastic line and support forces in statically indeterminate systems.
Elastic line under varying load.
Elastic line under various support conditions.
It is very suitable for the introduction and study of photoelasticity: optical elements, isochromatic, isoclinic, band order, band factor, edge tensionsing, and for strain and stress analysis and measurement with strain gauges.
Unit for photoelasticity practices, illustrating the subjects of the Photoelasticity theory, the Elasticity theory, Strength of Materials, and Structure theory.
Using this unit photoelastic experiments and practices of transparent test specimens (models) may be performed.
With the aid of the system it is possible to analyze and process the captured data during test experiments, making measurements with strain gauges.
These specimens show a full color and high contrast results and are also made of a special very hard material that avoids breaking during daily use.

The different test specimens are subjected to loading by external forces and have poralised light shone through them.
A load application element can apply tensile, bending, compressive, and distributed and punctual loads to the specimen.
It is very suitable for the introduction and study of photoelasticity: optical elements, isochromatic, isoclinic, band order, band factor, edge tensionsing, etc.
The stresses and strains occurring in the test specimen are represented as bright spots or figures of different colours, and we can visualise the distribution of stress.
This accessory set-up enables the response of an elastic rotor to unbalanced excitation to be studied. The field balancing of elastic rotors is another area which can be investigated. The supplied pendulum ball bearings ensure full mobility of the shaft. The subcritical, supercritical and resonance running states can be demonstrated. A comparison of the orbits (path curves) in the subcritical and supercritical range is of particular interest. The retainer bearing limits the amplitudes to harmless values at speeds close to resonance.
