Question

Which of the following is necessary for the complete study of surface roughness?

(a) Measurement of all the components of elements

(b) Analysis of all the component element

(c) Assessment of the effects of combined texture

(d) Measurement and analysis of all the components and assessment of combined texture

I have been asked this question in an internship interview.

My question is based upon Surface Roughness in portion Measurement of Surface Finish of Engineering Metrology

Answer 1

The correct answer is (d) Measurement and analysis of all the components and assessment of combined texture

For explanation: For the complete study of the surface roughness, it is important that the analysis and measurement of all the component elements be made and an assessment of the effects of the combined texture be made.
