Suppose that we have a vernier callipers which does not expand or contract on heating. Such a device is very useful in engineering applications where the dimensions are to be found at different temperatures. One such vernier callipers is used to measure the diameter of a rod at different temperatures as shown in table below. What will be the vernier scale reading (division coinciding) at a temperature of 50∘C.Given that 10 vernier scale divisions coincide with 9 main scale divisions and 1 main scale division is equal to 1 mm. Temperature T in ∘C 0 20 Main scale reading 2.4 cm 2.4 cm Vernier scale reading 4th division coinciding 8th division coinciding

Given that 10 vernier scale divisions coincide with 9 main scale divisions and 1 main scale division is equal to 1 mm.


















Temperature T in C 0 20
Main scale reading 2.4 cm 2.4 cm
Vernier scale reading 4th division coinciding 8th division coinciding
