Description
Experimental And Demonstration Polariscope
It is placed on an overhead projector (not supplied), with the image projected on to a screen, and, used either in a laboratory or a lecture theatre, allows a striking demonstration of the stress fields in the loaded models. It is also designed for quantitative work for tensile, compressive or flexural loading. A system – unique to this unit – also allows the simultaneous rotation of the polarizer and the analyser for the isoclinal lines study.
The Polariscope consists of the following elements :- A model-loading frame.
- An elastic load-measuring device, which uses a steel spring beam, and a micrometer dial gauge.
- The device has a linear deflexion/load relation-ship.
- A rotatable circular polarizing unit, in a graduated mount, carried on runners under the loading frame.
- A quarter ware plate.
- A rotatable circular analyser can be rotated through 180°.
The three units are carried on a pillar integral with the loading frame. The polarizer and the analyser are coupled so that they may turn simultaneously.
- A set of fixtures required for the application of the loads to all the models supplied.
- A set of models in the appropriate photo elastic material for example, a disk, a ring, a beam, etc.
- Polarizer diameter : 200 mm
- Model loading area : 190 x 220 mm.
- Light source : standard overhead projector source (white light). Monochromatic light obtained with green filter swung into path of light beam.
- Maximum load on models : ± 40 kg.
Teaching objectives
- Observation of the stress concentration.
- Study of strength of materials.
- Structures analysis in civil engineering
- Strength of materials.
- Structures, civil engineering and architecture.
- Applied mechanics, machine design, and welding technology.
- Soil mechanics.
- Biomechanics.
Dimensions and weight
- 420 x 320 x 350 mm.
- Net weight : 4 kg.
Essential requirements
- Additional Equipment required.
- Overhead projector.
Complementary equipment
- Analogue field plotters, 24 channels .
- This unit can be used in conjunction with the Polariscope for the separation of the principal stresses.
