Consider the vernier calipers as shown, the instrument has no zero error. What is the length of the rod (in mmmm) shown, if 1msd=1mm1msd = 1mm? Use 7msd=8vsd.7msd = 8vsd .

Consider the vernier calipers as shown, the instrument has no zero error. What is the length of the rod (in mm ) shown,

Correct answer

4.5

Step-by-step solution

7msd=8vsd7 \text{msd} = 8 \text{vsd}

⇒7vsd=78msd⇒ 7 \text{vsd} = \dfrac{7}{8} \text{msd}

⇒L.C=(1−78)mm=18mm⇒ \text{L.C} = \left(1 - \dfrac{7}{8}\right) \text{mm} = \dfrac{1}{8} \text{mm}

Were M.SR = 4 mm

V.S.R = 4

value value=(4+(4)(18))mm\text{value} = \left(4 + \left(4\right) \left(\dfrac{1}{8}\right)\right) \text{mm}

=4.5mm= \text{4.5} mm
