1. A wire of metal with a diameter of 1 cm and a length of 10 m is intended to be used to lift containers.
Find the maximum load that the wire can lift without the value of its elongation exceeding 3 cm? Note that
E for the wire is 10OGPA.
2. Draw a (perfect) stress-strain curve for a tensile test and show all the useful information on it.
3. Using drawing, define: 1. Ductility 2. Resilience
4. A sample of steel with a length of 50 mm was carried out with a tensile test until it was broken, and its
final elongation was 10 mm. Calculate the ductility of the sample?
5. A tensile test was carried out on a long proportional standard test piece of mild steel heat treated with a
circular diameter of 8 mm, and the load and elongation curves were as shown in the attached drawing.
Calculate the following: 1. Junk's modulus 2. Maximum yield stress 3. Minimum yield stress 4. Maximum
tensile strength 5. Stress of fracture 6. Resiliency 7. Modulus of resilience 8. Strength 9. Modulus of
toughness.
