Tensile Test Calculations

A tensile test specimen has a cross-sectional area of 100 mm². The force measured at the yield point was 41 kN and the maximum force was 42 kN. Calculate the following: The yield stress and the tensile strength.

The same tensile test showed that the force at the limit of proportionality was 40 kN and the extension was 0.095 mm over a gauge length of 50 mm. Calculate the modulus of elasticity.

A sample of material is stretched to destruction in a tensile test machine. The original area was 25 mm² and the original length was 50 mm. The final area and length was 16 mm² and 56.4 mm. The peak load reached was 32 kN. Determine the percentage reduction.
