Case-study: read the following micrometer

Solution

>> As, WHen Rotary Scale rotates by 50 division, linear scale moves by 0.5 mm

So, Least COunt of Micrometer = 0.5/50 = 0.01 mm

Case (a).

Reading is : 15 + 0.01*(35) = 15.35 mm ...ANSWER...

Case (b).

Reading is : 9.5 + 0.01*(18) = 9.68 mm ...ANSWER...

Case (c)

Reading is : 22 + 0.01*22 = 22.22 mm ....ANSWER...

Case (d).

Reading is : 0.5 + 0.01*33 = 0.83 mm ....ANSWER....

Case (e).

Reading is : 11 + 0.01*1 = 11.01 mm ...ANSWER....
