Question

Diagram shows stress-strain graph for two material A & B. The graphs are drawn to scale.
The ratio of young modulli of A to material B is

Answer 1

1. For given two graphs , the give strain for graph A is more than graph B. Hence Young's Modulus (=stress /strain) is greater for A than that of B
2. A is stronger than B strength of a material is measured by the amount of stress required to cause fracture.corresponding to point of fracture
