(1) What is determined while measuring a component?
Actual size
(2) Steel rule is a
direct reading measuring instrument
(3) Steel rule is made of
Stainless steel.
(4) Which of the following instruments is used for checking flatness and squareness of a surface?
Try square.
(5) Which of the following is an indirect measuring tool?
Inside caliper
(6)The base unit of length as per S.l. units are
meter
(7) The minimum measurement that can be read with the help of a steel rule is
0.50 mm
(8) Try square is used to check up an angle of
90°
(9) In a metric micrometer, a complete revolution of thimble advances
0.50 mm
(10) The least count of vernier bevel protractor is
5’
(11) The least count of the metric micrometer is
0.01 mm
(12) An outside micrometer has a negative error. The correct reading can be taken by
adding the negative error in the actual reading.

(15) The minimum measurement that can be correctly read with a vernier caliper is called
least count
(16) Metric outside micrometer has a threaded spindle with a pitch of
0.5 mm
(17) Zero error in micrometer means
zero on thimble and datum line on sleeve do not coincide when measuring faces are in contact
(18) Lock nut in the micrometer is provided to
lock the reading after setting it over the workpiece
(19) Micrometer works on the principle of
nut & bolt

Rack and pinion mechanism
(22) Ratchet stop in the micrometer helps to
control the pressure
(23) Least count of the vernier caliper is equal to
value of 1 M.S.D - a value of 1 V.S.D.
