A graph is drawn between stress and strain of a wire. Predict the correct statement.
1 Region I is called as plastic region
2 Region II is called as elastic region
3 Along the path \(O \rightarrow Q\) the body regain its shape after removing the load
4 The Hooke's law is obeyed from \(P \rightarrow Q\)
Explanation:
Region I is called as elastic region where as region II is called as plastic region. The wire regains its shape only in the elastic region. the hooke's law is obeyed between \(O \rightarrow P\)

The stress-strain graph for materials \({A}\) and \({B}\) are shown in the figure. Graphs are drawn to the same scale. Which of the two is the stronger material?
1 \({A}\)
2 \({B}\)
3 Both are equally strong
4 None of these
Explanation:
Strength of material is determined by amount of stress required to fracture the material. So correct option is (1).

Read the Assertion and Reason carefully to mark the correct options given below: Assertion : Steel is used in the construction of buildings and bridges. Reason : Steel is more elastic and its elastic limit is high.
1 Both Assertion and Reason are correct but Reason is NOT the correct explanation of Reason.
2 Both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
3 Assertion is correct but Reason is not correct.
4 Assertion is not correct but Reason is correct.
Explanation:
A body is said to be more elastic depending upon how fast it gains its original shape after removal of external force. When a force is applied to steel, it is deformed but it immediately regains its original shape. The modulus of elasticity (or Young's modulus) of steel is greater. Hence it is used in the construction of buildings and bridges. So , correct option is (2).
