Solid Mechanics and Fluid power Lab Manual

I Solid Mechanics Laboratory

1. Test on Ductile Materials:
   Finding Young’s modulus of elasticity, yield points, percentage elongation and   percentage  reduction in area, stress-strain diagram plotting, tests on mild steel and cast iron.
2. Hardness Test:
   Determination of Rock well’s hardness number for various materials like mild   steel,  high  carbon steel, brass, copper and aluminum. 
3. Torsion Test:
   Torsion test on mild steel – relation between torque and angle of twist-  determination of shear modulus-determination of elastic constants for mild steel.
4. Bending and deflection Tests :
   Determination of Young’s modulus for steel by deflection test.
5. Impact Test :
   Finding the resistance of materials to impact loads by lzod test or Charpy test.
6. Tests on springs of circular section :
   Determination of modulus of rigidity, strain energy, shear stress by load deflection method – Compression and tension test (Closed coil spring only)
7. Shear Test :
   Shear test on M.S bar.
