Elastic deformation — practice question

Fig. 1.1 illustrates a steel spring.
(a)[3]

Describe an experimental procedure for obtaining the data required to plot an extension-load graph for this spring.

(b(i))[2]

Using Fig. 1.2, sketch the extension-load graph for this spring.

(b(ii))[1]

On your graph in Fig. 1.2, mark the limit of proportionality and label it P.

(c)[2]

For this spring, the limit of proportionality is reached at a load of 8.5 N. When the load is 3.5 N, the spring’s extension is 0.014 m. Calculate the extension for a load of 5.5 N.
