Engineering Metrology Questions and Answers – Clinometers

This set of Engineering Metrology Multiple Choice Questions & Answers (MCQs) focuses on “Clinometers”.

1. At which part spirit level is present in the clinometers?
a) On a rotary member
b) On the fixed member
c) On the base
d) On the circular scale
View Answer

Answer: a
Explanation: A special case of the application of spirit level is a clinometer. The spirit level is mounted on a rotary member present in the clinometer carried in housing. One face of the housing forms the base of the clinometer.

2. At which interval, circular glass is divided in Hilger and Watts type clinometers?
a) 3’
b) 5’
c) 10’
d) 2’
View Answer

Answer: c
Explanation: Hilger and Watts type is the most commonly used clinometer. The circular glass scale is enclosed. It is divided from 0 degree to 360 degree at 10′ intervals. An optical micrometer can be used for the subdivision of 10′.

3. Which of the following is not a common function of clinometers?
a) Determine included angle of two adjacent faces
b) Checking angular faces
c) Checking relief angles on small cutting tools
d) Setting inclination table
View Answer

Answer: c
Explanation: Clinometers can be used for checking relief angles on large cutting tools, for checking angular faces and milling cutter inserts. These can also be used on jig boring machines for setting inclination table and on grinding machines for angular work.

4. What is the range of readings which can be read directly in precision microptic clinometer?
a) 0o to 180o
b) 0o to 270o
c) 0o to 90o
d) 0o to 360o
View Answer

Answer: d
Explanation: Precision microptic clinometer can be used for direct reading over the range 0° – 360°. Special feature of precision microptic clinometer are optical reading system, totally enclosed glass circles, slow motion screw for fine adjustments, eyepiece rotatable to most convenient viewing position.

5. Which of the following is used to illuminate scale in precision microptic clinometer?
a) An integral low voltage lamp
b) An integral high voltage lamp
c) An ordinary lamp
d) A high voltage bulb
View Answer

Answer: a
Explanation: The scales of precision microptic clinometer are illuminated by an integral low voltage lamp. Daylight illuminated bubble unit is present, but is also provided with a lamp. It is for alternative illumination.

6. What is the purpose of slow motion screw in precision microptic clinometer?
a) To set tool head initially
b) Same function as of locating face
c) Final adjustment to centre the bubble
d) Measure angle between the surfaces
View Answer

Answer: c
Explanation: The clinometer can be used as a precision setting tool. It can be used to set a tool head or table at a given angle. Micrometer scale is set firstly. Then the glass scale is rotated. It is to bring the relevant graduation to the index, for final adjustment the slow motion screw is used.

7. Which of the following is not a part of index head of centers used in clinometer?
a) Indexing plate
b) Camshaft
c) Crank
d) Worm and worm wheel
View Answer

Answer: b
Explanation: The index head of the centers mainly consists of indexing plate, a crank and worm and worm wheel. The crank is attached to a worm. Worm is in mesh with the worm wheel.

8. Index centres are actually meant to use on which machine?
a) Milling machines
b) Planer machines
c) Lathe machines
d) Shaper machines
View Answer

Answer: a
Explanation: Index centres were meant for the use on milling machines. But now their application is extended to inspection work. In such cases, where the measurement of a large number of angular dimensions about a common centre is required, index centres are best suited.

9. What is the purpose of locating face present on the back of the precision microptic clinometer?
a) Allows instrument to be used vertically
b) Allows instrument to be used at an angle
c) Allows instrument to be used horizontally
d) Allows the setting of inclination table
View Answer

Answer: c
Explanation: With the suitable accessories these clinometers can be used for measuring angular displacements of small part. A locating face is present on the back of the precision microptic clinometer which allows the instrument to be used horizontally with the reflector unit or accessory worktable.

10. What is the use of worm and quadrant arrangement in clinometers?
a) Reading up to 5’ is possible
b) Reading up to 1’ is possible
c) Reading up to 10’ is possible
d) Reading up to 0.1’ is possible
View Answer

Answer: b
Explanation: Worm and quadrant arrangement is provided in some instruments so that reading up to 1′ is possible. There is no bubble present in some clinometers but a graduated circle is present and it is supported on accurate ball bearings.

11. Which of the option is true for the given statements about clinometers?
Statement 1: Bubble vial is the reference for inclination.
Statement 2: It can’t be used for angular work on grinding machines.
a) T, F
b) F, F
c) F, T
d) T, T
View Answer

Answer: a
Explanation: Bubble vial is the reference for inclination. To measure the inclination of a surface, the vial is turned until it is approximately level. After this, the slow motion screw is used to centre the bubble.
