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.
