1.1. A student carries out an experiment which will enable them to draw a suitable graph in order to obtain a value for the Young’s modulus of a wire.

Label the apparatus shown in Figure 1 which would enable the student to obtain a value of the Young’s modulus of the wire. 

Figure 1

1.2. State and explain safety consideration when carrying out the experiment using the apparatus you have drawn in part (a).

1.3. On the axis of Figure 2 draw a graph to show the relationship between the stress and strain values which the pupil could obtain from the experiment.

Assume that the wire is not stretched beyond the limit of proportionality.

Figure 2

1.4. State how the Young modulus value could be obtained from the graph in Figure 2.
