1. Tensile test can be performed on _____________
a) Impact testing machine
b) Universal testing machine
c) Rockwell tester
d) Brinell tester
View Answer

Answer: b
Explanation: Tensile testing, also known as tension testing, is a fundamental material science test in which a sample is subjected to a controlled tension until failure.

a) Impact testing machine
b) Universal testing machine
c) Rockwell tester
d) Brinell tester
View Answer

Answer: b
Explanation: A universal testing machine (UTM), also known as a universal tester, materials testing machine or materials test frame, is used to test the tensile strength and compressive strength of materials.

4. In universal testing machine, for a circular section specimen, the gauge length is taken to be ______________
a) 3.65 √A
b) 4.65 √A
c) 5.65 √A
d) 6.65 √A where A is the area of cross section of the specimen
View Answer

Answer: c
Explanation: It is the formula to find the gauge length when we have the area of the specimen.

8. The indenter used in Brinell hardness test is a ____________
a) Ball
b) Cone
c) Cylinder
d) Pyramid
View Answer

Answer: b
Explanation: The Brinell method applies a predetermined test load (F) to a carbide ball of fixed diameter (D) which is held for a predetermined time period and then removed.

9. For hardness test of copper in Brinell hardness tester, the diameter of ball is ___________
a) 7mm
b) 1mm
c) 5mm
d) 3mm
View Answer

Answer: c
Explanation: ASTM E-10 is a standard test for determining the Brinell hardness of metallic materials. The load applied in this test is usually 3,000, 1,500, or 500 kgf, so that the diameter of the indentation is 5 mm.

a) 30 degrees
b) 45 degrees
c) 60 degrees
d) 90 degrees
View Answer

Answer: b
Explanation: In charpy test specimen, the angle of v-notch section is 45 degrees and 0.25mm radius along the base.
