  1. A tensile test sample has a gauge length of 10 cm and a cross-section area of 500 mm2. During the test, the sample yields at 0.2 % strain under a load of 1.5 x 105 N and the corresponding gauge length is 10.1 cm. The maximum load of 2 x 105 N is reached at a gauge length of 13 cm and the fracturing cross-section area is 370 mm2.

    Determine the values of (a) yield strength, (b) modulus of elasticity, (c) tensile strength, (d) modulus of resilience, (e) the percent elongation and (f) the percent reduction in area.
