Q1. In a world filled with uncertainty, he was glad to have many good
friends. He had always assisted them in times of need and was
confident that they would reciprocate. However, the events of the last
week proved him wrong. Which of the following inference(s) is/are
logically valid and can be inferred from the above passage?
(i) His friends were always asking him to help them.
(ii) He felt that when in need of help, his friends would let him down.
(iii) He was sure that his friends would help him when in need.
(iv) His friends did not help him last week
Answer : Option B
Explaination / Solution:
The paragraph states that the subject was very
confident about his good friends helping him in his times of need
because he had always helped them before in their time. Thus,
inference iii follows.
Since the events of the last week proved him wrong, this means that
his confidence was broken and his friends had not helped him. Thus
inference iv also follows.
Q2. The “Jominy test” is used to find
Answer : Option B
Explaination / Solution:
Jominy Test measures the hardenability of the steels.
Q3. The policeman asked the victim of a theft, “What did you
Answer : Option B
Explaination / Solution:
The context of the sentence is asking a person who has been
deprived of something because of a theft. The word to be used to fill
the blank is ‘lose’ which means to be deprived of something. ‘Loose’
means something that is not fitted. ‘Louse’ is the singular form of the
word ‘lice’ that is a parasite that lives in the skin of mammals and
birds. ‘Loss’ is a noun that means the process of losing someone or
something. Eg: He suffered tremendous loss in his business.
Q4. Under optimal conditions of the process the temperatures
experienced by a copper work piece infusion welding, brazing and
soldering are such that
Answer : Option D
Explaination / Solution:
Under the optimal conditions temperature of different processes
experienced by a copper work piece is given by
Twelding > Tbrazing > Tsoldering
Q5. Which of the following statements are TRUE with respect to
heat and work?
(i) They are boundary phenomena
(ii) They are exact differentials
(iii) They are path functions
Answer : Option B
Explaination / Solution:
Since, Heat and work are the path function and these are
not the property of system. Hence exact different of Heat and work
will not be zero. So, Heat and Work are the inexact differential.
Also, heat and work are the energy in transit or boundary
phenomena.
Q6. The part of a gating system which regulates the rate of pouring
of molten metal is
Answer : Option C
Explaination / Solution:
Rate of poring molten metal is regulated by choke. As, the choke area
is the minimum area of the gating system, which decide the gating
will be pressurised and unpressurised (or turbulence will occur or
not). Hence, choke is the part which regulate the rate of pouring.
Q7. The non-traditional machining process that essentially
requires vacuum is
Answer : Option A
Explaination / Solution:
In electron- beam machining, vacuum conditions are
created/required for material removal, because electrons move
efficiently in vacuum.
Q8. Match the following:
P. Feeler gauge I. Radius of an object
Q. Fillet gauge II. Diameter within limits by comparison
R. Snap gauge III. Clearance or gap between components
S. Cylindrical plug gauge IV. Inside diameter of straight hole
Answer : Option A
Explaination / Solution:
No Explaination.
Q9. The instantaneous stream-wise velocity of a turbulent flow is
given as follows:
The time-average of the fluctuating velocity u’(x, y, z, t) is
Answer : Option C
Explaination / Solution:
No Explaination.
Q10. For a floating body, buoyant force acts at the
Answer : Option D
Explaination / Solution:
Buoyancy force is the force due to displaced volume of water. Hence,
buoyancy force always act on the centroid of displaced volume.
