Functional Characteristics:  

This instrument is used in the experiment of material mechanics and electrical measurement in colleges and universities. It can complete more than ten kinds of tests of teaching syllabus.  Which has stronger integrity, small space occupation, safe and simple operation than single-function experimental device. Tests including:

1. Experiment on the distribution of normal stress on the section of pure bending beam

2. The affection of strain distribution of superposed beam of stress distribution, superposed beam boundary conditions changing

3. Testing of material elasticity modulus E,  poisson’s ratio

4. Bias tesile testing

5. Hollow cylinder torque testing of shear elasticity G

6. Force analysis of crankle combination

7. Constant strength beam testing

8. Straight beam bending test

9. Measuring bridge testing

10. Deflection testing

11. Calibration test of strain gage sensitivity

12. Principal stress test of strain rosette

13. Compressive test
