1. The total number of scales used in Rockwell hardness test is?

12 14 15 16

15

There are 15 scales used in Rockwell hardness test, which are being differentiated based on indenter used and material sampled.

Hint Answer

2. Vickers hardness test has a scale range of _________

0 to 10 100 to 200 0 to 1000 0 to 3000

0 to 3000

Vickers hardness test has a scale range of 0 to 3000. It is used to measure hardness of a specimen.

Hint Answer

3. Rockwell hardness test has a scale range of _____

0 to 10 100 to 200 0 to 1000 0 to 3000

0 to 1000

Rockwell hardness test has a scale range of 0 to 1000. It is used to measure hardness of a specimen.

Hint Answer

4. According to BS standard, which of following relation is correct about gauge length of cross section area ‘A’?

L = 2.51\(\sqrt{A}\) L = 4.51\(\sqrt{A}\) L = 4\(\sqrt{A}\) L = 3.51\(\sqrt{A}\)

L = 4\(\sqrt{A}\)

According to BS standard, gauge length = 4\(\sqrt{A}\), where A denotes cross section area of specimen used under testing.

Hint Answer

5. Permanent deformation of material with respect to time due to constant load and variable temperature is termed as ________

Elasticity Isotropy Hardness Creep

Creep

Creep is time and temperature dependent phenomenon. With passage of time and or environmental condition, material may lead to fracture point.

Hint Answer

6. Which of following property will be more in fine grained structure?

Ductility Corrosion resistance Creep resistance Hardness

Ductility

Finer grain size (lower grain size), more is number of grain boundaries, thus more is yield strength, thus more is ductility. This is reason why we can easily draw a fine-grained structure into wires.

Hint Answer

7. Which of following compound is used for fine polishing?

Aluminum oxide Nitric oxide Silicon carbide Iron oxide

Aluminum oxide

Powder form of aluminum oxide is used for fine polishing process. It is surface treatment process.

Hint Answer

8. In which of following test specimen is in form of simply supported beam?

Izod test Rockwell hardness test Charpy test Brinell test

Charpy test

In Charpy test a supported beam specimen is used.

Hint Answer

9. Which of following non destructive testing is used to detect change in composition of any material?

Liquid penetration test Ultrasonic test Eddy current test Radiography

Radiography

Radiography enables us to detect change in composition. X-rays or ?-rays are used in radiography technique.

Hint Answer

10. Equipment used for inspection of inside portion of hollow chamber or narrow tube is known as _______

Endoscope Telescope Borescope Flexiscope

Borescope

Borescope is used for visual of inside portion of hollow chamber.
