MCQs on Radius Gauges
1 - Question
Which of the following is another name of radius gauge?
a) Ring gauge
b) Planer gauge
c) Fillet gauge
d) Plug gauge
View Answer
Answer: c
Explanation: Fillet gauge is another name of radius gauge. Fillet gauges are used to check the radius of an object. Radius gauges can also be used for inspection work.
2 - Question
Why a radius is provided at the meeting point of two surfaces?
a) To reduce material
b) To avoid collision
c) To increase stability
d) To avoid stress concentration
View Answer
Answer: d
Explanation: Sharp corners are subjected to more stress. So, to avoid stress concentration, radius is provided.
3 - Question
Which of the following option is incorrect with respect to radius gauges?
a) Concave radius is an internal radius
b) Radius gauges are used for final inspection
c) If the curved surface is external then this radius is known as female radius
d) Radius gauges are suitable for both fillet and radius measurement
View Answer
Answer: c
Explanation: If the curved surface is external then it is called male radius or simply radius. Term Female radius is used for internal curved surface.
4 - Question
Match the following:
A) Precision polygons - 1) Indexing B) Radius gauge - 2) Checking known angles C) Dividing head - 3) Measure concave surfaces D) Sine bar - 4) Calibration of rotary table
a) A-1, B-3, C-2, D-4
b) A-4, B-3, C-1, D-2
c) A-3, B-2, C-4, D-1
d) A-2, B-1, C-3, D-4
View Answer
Answer: b
Explanation: Precision polygons are used to calibrate dividing heads and rotary tables. Radius gauges are used to measure and check concave and convex surfaces. Sine bars are used to locate work at a given angle. Sine bars are also used to measure known and unknown angles.
5 - Question
Which of the following option is true for given statement?
Statement 1: For gauging the radius, a light source is used with radius gauge.
Statement 2: Pitch of the threads can be measured by radius gauge.
a) T, F
b) T, T
c) F, T
d) F, F
View Answer
Answer: a
Explanation: A light source is used with radius gauges. Work is placed between light source and eye. It is the light passage due to which work can be gauged properly. To determine thread pitch, pitch screw gauge are used.
6 - Question
What is another name of blades of radius gauge?
a) Leaf
b) Petal
c) Cutter
d) Scale
View Answer
Answer: a
Explanation: Each radius gauge has a number of blades. These blades are also known as leaves. Leaves can be used in any position to measure radius.
7 - Question
Which of the following is not a type of radius gauge?
a) Acrylic
b) Guitar
c) Digital
d) Planer
View Answer
Answer: d
Explanation: Planer gauge is a measuring instrument which is used to measure slot width and setting tool height. It has two triangular blocks whose sides can be clamped.
8 - Question
What is the measuring range for radius gauge?
a) 0.00075-0.025 m
b) 0.0075-0.5m
c) 0.075-5m
d) 0.75-5m
View Answer
Answer: a
Explanation: Measuring range of radius gauge is generally 0.00075 to 0.025 meter. The blades are specially shaped and can be used to measure fillets and radius against shoulders or corners.
