Question

1. Determine the least count of vernier calipers and measure the length and diameter of a small cylinder (average of three sets) of a metal rod.

Answer 1

To determine:

The least count of vernier calipers and measure the length and diameter of a small cylinder (average of three sets) of a metal rod.

Calculation:

Least count of vernier caliper is denoted as LC;

$\boxed{ \sf{LC = \dfrac{smallest \: division \: of \: main \: scale}{total \: divisions \: of \: vernier \: scale} }}$

Putting the values for a standard Vernier Calliper:

$= > \sf{LC = \dfrac{1 \: mm}{10} }$

$\boxed{ = > \sf{LC = 0.1 \: mm}}$

So, diameter of the cylinder can be calculated as:

$\boxed{ \sf{\therefore \: d = MSR +(LC \times VSR)}}$

Average diameter:

$\boxed{ \sf{d \: avg. = \dfrac{d1 + d2 + d3}{3} }}$

Similarly , length can be calculated as:

$\boxed{ \sf{\therefore \: l = MSR +(LC \times VSR)}}$

Average length:

$\boxed{ \sf{l \: avg. = \dfrac{l1 + l2 + l3}{3} }}$

Hope It Helps.
