Question

A screw gauge has 1.0mm pitch and 200 divisions on circular scale. L c is

Answer 1

Least count = Pitch / Number of divisions on circular scale

From the formula, it is clear that by increasing the number of divisions on circular scale. Least count can he decreased, hence the accuracy will increase.

It is correct theoretically but practically it may not be possible because it is difficult to take the reading precisely as the resolution of human eye is not so high.

Answer 2

Answer:

Answer :

Least count = Pitch / Number of divisions on circular scale

• From the formula, it is clear that by increasing the number of divisions on circular scale. Least count can he decreased, hence the accuracy will increase.
• It is correct theoretically but practically it may not be possible because it is difficult to take the reading precisely as the resolution of human eye is not so high.
