GATE 2020 ME (ME2) – Question 22

Metrology and Inspection · Interferometry, form and finish measurement · 1 mark · Multiple choice

The figure symbolically represents surface texture in a perpendicular lay orientation. I–VI mark specification positions. P: Maximum waviness height (mm); Q: Maximum roughness height (mm); R: Minimum roughness height (mm); S: Maximum waviness width (mm); T: Maximum roughness width (mm); U: Roughness width cutoff (mm). Match the specifications to I–VI.

Show answer and explanation

Correct answer: (A) I–R, II–Q, III–P, IV–S, V–U, VI–T

Explanation

The stacked left-side entries set minimum and maximum roughness height (I=R,II=Q). The upper paired values specify maximum waviness height and width (III=P,IV=S). The central value V is roughness cutoff U, and the lower right VI is maximum roughness width T. **Answer:A**. Match positions rather than alphabetic order.
