Question

1. using the pictures of the callipers, determine the measurement to the hundredth of a millimetre. a. reading: _

Explanation:

Step1: Identify main - scale reading

The main - scale reading is the value on the fixed scale. Here, the main - scale reading is 50 mm.

Step2: Identify vernier - scale reading

The vernier - scale division that aligns best with a main - scale division is the vernier reading. Each vernier division represents 0.02 mm. The 12th vernier division aligns with a main - scale division. So the vernier reading is \(12\times0.02 = 0.24\) mm.

Step3: Calculate total reading

The total reading is the sum of the main - scale reading and the vernier - scale reading. So, \(50+0.24 = 50.24\) mm.

Answer:

50.24 mm
