The stress-strain graphs for materials A and B are shown in figure.
(a) Which of the materials has the greater Young’s modulus?
(b) Which of the two is the stronger material?
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?
Solution:
(a) Material A has greater value of Y. It is because, for producingsame strain, more stress is required in case of material A.
(b) Material A is the stronger of the two materials. It is because, it can bear greater stress before the wire of this material breaks.
(b) Material A is the stronger of the two materials. It is because, it can bear greater stress before the wire of this material breaks.
