Figure 3 illustrates the stress-strain diagram for tensile test of four (4) different materials and labelled as A, B, C and D. Each tested sample is 10 mm in diameter with a gauge
length of 50 mm. From the diagram,
i)
) Identify the material with the largest modulus of elasticity and state its value.
[2 Marks]
ii) Identify the material with the maximum ultimate tensile strength and state its value.
[2 Marks]
iii) Identify the material with the highest failure strength and state its value.
[2 Marks)
iv) Identify the material with the lowest yield strength and state its value.
[2 Marks]
v) Predict the suitable material among A, B, C and D for the used in construction.
Give TWO (2) reasons.
