25) Ratchet stop in the micrometer helps to

Answer is:

Control the pressure

Explanation:

Ratchet stop is present at the end of thimble cap to maintain a uniform measuring pressure. By ratchet stop standard conditions of measurement are attained.

26) The least count of the vernier caliper is equal to

Value of 1 M.S.D. - value of 1 V.S.D.

Value of 1 V.S.D. - value of 1 M.S.D.

Value of 2 M.S.D. - value of 1 V.S.D.

Value of 1 M.S.D + value of 1 V.S.D.

Answer is:

Value of 1 M.S.D. - value of 1 V.S.D.
