Figure 8.9 shows the strain-stress curve for a given material. What are (a) Young’s modulus and (b) approximate yield strength for this material?

The stress-strain graphs for materials A and B are shown in Fig. 8.10.

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?
Consider the following four words, out of which three are alike in some manner and one is different.
(A) Arrow
(B) Missile
(C) Sword
(D) Bullet
Choose the combination that has alike words.
