EXERCISES

1. Study of construction and use of Universal Testing Machine, mechanical and optical extensometers- application to detremine stress-strain curves and tensile and compressive strength of various engineering materials.
2. Bending tests- deflection of slender and short beams for various loading and end conditions- detremination of influence coefficients- verification of Maxwell's and Castigliano's theorems.
3. Compression tests on long and short columns- determination of buckling loads- Southwell plot.
4. Determination of the strength and deformation of riveted and bolted joints.
5. Methods of inspection and non-destructive testing (NDT) of aircraft structual components.
6. Strain gauge techniques- measurement of strain in beams, thin and thick walled cylinders subjected to internal pressure, shaft subjected to combined loading.
7. Shear Centres of open and closed sections- determination of the elastic axis of beams.
8. Post buckling behaviour of shear panels- measurements on semi-tension field webs of beams.
9. Determination of elastic constants of composite materials- flexural test on composites.
10. Study and calibration of photo and magnetic speed pickups for the measurement of speed.
11. Study and use of seismic pickups for the measurement of amplitude and frequency of vibration of structural components.
12. Determination of critical frature toughness of aerospace materials.
