Question

As we've discussed, one model of material deformation links stress and strain

Answer 1

Material 1 will be having the largest Young's modulus followed by Material 5, Material 3, Material 2 and Material 4.

Answer:

Option C.

Explanation:

Materials can be classified based on their elastic nature. Elasticity is the property of an object to return to its original state after deformation is removed. So the deformation can be occurred on that object due to the force or stress acting on that object.

As per Hooke's law, the stress acting on any object is directly proportional to the deformation or strain experienced by that object. And the constant of proportionality is termed as Young's modulus.

Young's modulus = Stress/Strain

So from the table, the young's modulus for all the materials are found as below.

Material 1 = Stress/Strain = 775/7.34E-06 = 106 ×$10^{6}$

Material 2 = 900/1.86E-02=48400

Material 3 = 1200/2.55E-05 = 471×$10^{5}$

Material 4 = 1500/3.95E-03=389×$10^{3}$

Material 5 = 2500/2.53E-05=988×$10^{5}$

So as per the given calculations, Material 1 will be having the largest Young's modulus followed by Material 5, Material 3, Material 2 and Material 4.
