Q6. 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
Q7. 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.
Q8. 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.
Q9. 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.
Q10. A cube shaped casting solidifies in 5 minutes. The solidification time in minutes for a cube of the same material, which is 8 times heavier than the original casting will be
Answer : Option B
