Question 171. 3. A master gauge is
  1.    A new gauge
  2.    An international reference standard
  3.    A standard gauge for checking accuracy of gauges used on shop floors
  4.    A gauge used by experienced technicians
 Discuss Question
Answer: Option C. -> A standard gauge for checking accuracy of gauges used on shop floors
Question 172. 0. Diametral gauging for out-of-roundness measurement is not sufficient because
  1.    It can't sense even lobed parts
  2.    Radial changes always occur which can't be sensed by it
  3.    It is difficult to find true centre
  4.    Its readings can't be fed to computer
 Discuss Question
Answer: Option B. -> Radial changes always occur which can't be sensed by it
Question 173. 2. Pick out the wrong statement about measuring out-of-roundness by V-block gauging.
  1.    60 degree V-block provides triple magnification of out-of-round characteristics of 3 lobed part.
  2.    With a V-block, ovality and other even-numbered lobing are magnified.
  3.    For checking a five lobed part, 108? V is required
  4.    The use of a series of V blocks would not necessarily detect all types of outof-roundness.
 Discuss Question
Answer: Option B. -> With a V-block, ovality and other even-numbered lobing are magnified.
Question 174. 4. Gear tooth vernier is used to measure
  1.    Gear tooth profile
  2.    Gear tooth thickness
  3.    Pitch line thickness of gear tooth
  4.    Module
 Discuss Question
Answer: Option C. -> Pitch line thickness of gear tooth
Question 175. 5. Moire fringes are observed when
  1.    An optical flat is placed over smooth surface
  2.    A microscope is used to observe surface texture
  3.    Index grating is moved over scale grating
  4.    White light is diffused through _ a prism
 Discuss Question
Answer: Option C. -> Index grating is moved over scale grating
Question 176. 6. The surface roughness on a drawing is represented by
  1.    Circles
  2.    Squares
  3.    Zig-zag lines
  4.    Triangles
 Discuss Question
Answer: Option D. -> Triangles
Question 177. 8. Electronic level contains
  1.    A pendulum
  2.    Spirit level (c)
  3.    Micrometer (d) clinometer
  4.    (e) sine bar.
 Discuss Question
Answer: Option A. -> A pendulum
Question 178. 9. Keilpart gauge is used to measure
  1.    Surface roughness
  2.    Taper
  3.    Inside diameter Of a tool
  4.    Gear eccentricity
 Discuss Question
Answer: Option C. -> Inside diameter Of a tool
Question 179. 2. Gratings are used in connection with
  1.    Flatness measurement
  2.    Linear displacement measurements.
  3.    Surface texture measurement
  4.    Convexity/concavity measurement
 Discuss Question
Answer: Option B. -> Linear displacement measurements.
Question 180. 0. In interferometric methods, the path difference between one bright band and the next is varied by
  1.    Half wave length
  2.    Two half wave lengths
  3.    One quarter wavelength
  4.    Two wavelengths
 Discuss Question
Answer: Option B. -> Two half wave lengths
