APPLIED MECHANICS LABORATORY

OBJECTIVES

     

  • Making of mechanism and proving of Verignon’s theorem by taking actual measurement of moments.
  • To measure impact strength, tensile strength, compressive strength, hardness and ductility.
  • To measure properties such as modulus of elasticity, yield strength, ultimate strength for the given materials.
  • To determine the coefficient of friction.
  • Determination of torsional rigidity of materials.
