Section B: (10 marks)

Answer the following question.

1. A pair of vernier calipers is used to measure the

external diameter of a water pipe. Figure 2.1shows the

main and vernier scales of the vernier calipers when thewater pipe is lightly closed by the jaws.

(a) Determine the vernier caliperreading. [2 marks]

Figure 2.1

Before the vernier caliper is used, the jaws are closed.Figure 2.2 shows the main and vernier scales of the vernier

calipers with the jaws closed.

(b) Name this systematic error in the vernier calipers.[2 marks]

Figure 2.2

(c) State the reading of the error. [2 marks]

(d) This error can be taken into account by adding it or

subtracting it from the reading obtained. Determine

the actual reading of the external diameter of thewater pipe. [4 marks]
