1.	The stress-strain graphs for materials A and B The graphs are drawn to the same scale. (a) Which of the materials has the greater Young's modulus ? (b) Which of the two is the stronger material ?
Answer» SOLUTION :It is clear from both the grpah that for material A. Slope of graph`= (("Stress")/("STRAIN"))` is greater. Hence YOUNG modulus `(("Stress")/("Strain"))` of material A is more. (b) The amount of stress required for fracting a material, corresponding to its fracture point GIVES the strength of material. Material A can withstand more strain than material B. Hence, material A is stronger than material B.
