The circular scale of a screw gauge has ...

The circular scale of a screw gauge has 50 divisions and pitch of 0.5 mm. Find the diameter of sphere. Main scale reading is 2.

A

1.2 mm

B

1.25 mm

C

2.20 mm

D

2.25 mm

Text Solution

Verified by Experts

The correct Answer is:
a
Least count `=("Pitch")/("Number of division on circuit scale")=0.5/50`
`=0.01 mm`
Now, diameter of ball `=(2xx0.5)+(2.5-5)(0.01)=1.2 mm`
