- QUESTION ONE (a) Distinguish between physical and mechanical properties of materials. Give two examples of each. (b) Explain why in a stress versus strain curve, the plastic portion of the graph after necking tends to drop (ie the force drops) despite that the tension is increasing. (c) A tensile test uses a copper test specimen that has a gauge length of 80 mm and a di.ameter of 16 mm. During the test, the specimen yields under a load of 9,600 N. The corresponding gauge length is 80.24 mm. The maximum load reached is 148,000 N at a gauge length of 94.2 mm, while fracture happens at a load of 12,800 N and a gauge length of 102 6 mm Determine the following: (i) Modulus of elasticity E (ii) Yield strength Oy (iii) Fracture strength, ơt (iv) Tensile strength OTs. 1arrow_forwardThe data shown in the table below were obtained from a tensile test of high-strength steel. The test specimen had a diameter of 13mm and a gage length of 50mm. At fracture, the elongation between the gage marks was 3.0mm and the minimum diameter was 10.7mm. Plot the conventional stress-strain curve for the steel and determine the propotional limit, modulus of elasticity (i.e the slope of the initial part of the stress-strain curve), yield stress at 0.1% offset, ultimate stress, percent elongation in 50mm, and percent reduction area.
