**CE1256 STRENGTH OF MATERIALS LABORATORY 0 0 3 100**

**OBJECTIVE**

The experimental work involved in this laboratory should make the student understand the fundamental modes of loading of the structures and also make measurements of loads, displacements and strains. Relating these quantities, the student should be able to obtain the strength of the material and stiffness properties of structural elements.

**LIST OF EXPERIMENTS**

1. Test involving axial compression to obtain the stress – strain curve

2. Test involving axial tension to obtain the stress – strain curve and the strength

3. Test involving torsion to obtain the torque vs. angle of twist and hence the stiffness

4. Test involving flexure to obtain the load deflection curve and hence the stiffness

5. Tests on springs

6. Hardness tests

7. Shear test

8. Test for impact resistance

The student should learn the use of deflectometer, extensometer, compressometer and strain gauges.
