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.

1. A specimen of an unknown material is subjected to tensile
test. It presents a square Cross-Section (36 mm on each side) and
an initial length of 161 mm. Once it is pulled in tension to a load
of 72,472 N, it experiences an elongation of: 0.44 mm.
Assuming an elastic behavior, determine Young's Modulus for this
material (in GPa).

A tensile test is done on a tensile specimen with a gauge
diameter of 8 mm and gauge length of 45 mm was tested at a
temperature above the recrystallization temperature. The test was
done at a constant speed of 8 mm/min, strength constant C = 210MPa
and strain rate sensitivity exponent m = 0.22. As the gauge length
extends to 80 mm then find:
