Which of the following is not part of important factors which are required to be considered for selection of exact plant location?
A)
Easy access
B)
Availability of cheap, sufficient and suitable land
C)
Cost of material required for construction
D)
None of these
For selecting an exact plant location, important factors usually include easy access, availability of cheap/sufficient/suitable land, transportation, labour, water, power, and market proximity. The cost of material required for construction is not a primary site-selection factor; it is more related to project budgeting and construction planning. Therefore, option (c) is the correct answer. Option (a) and (b) are valid location factors, so (d) is incorrect.
A governor is a device
A)
to control temperature variation
B)
to slowdown the speed
C)
to control speed variation in an engine and controls the amount of fuel to an engine to match the load requirement to maintain in a specific speed
D)
None of these
A governor is used in engines to automatically regulate the engine speed when load changes. It does this by adjusting the fuel supply so that the engine speed remains nearly constant. Option (a) is unrelated, and (b) is too vague and incorrect because a governor does not simply slow down speed; it maintains speed. Hence, (c) is correct.
Certain statistical techniques have been derived to evaluate machines, materials and processes by observing capabilities and trends so that continual analysis and predictions may be made to control the desired quality level. The statistical techniques are called
A)
Fundamental of statistics
B)
Statistical quality control methods
C)
Sampling inspection
D)
None of these
The question describes statistical techniques used to evaluate machines, materials, and processes by observing variation, capabilities, and trends to maintain and control quality. This is the definition of Statistical Quality Control (SQC) methods.
- (a) Fundamentals of statistics: too broad; not specifically for quality control.
- (b) Statistical quality control methods: correct, because SQC uses statistical tools to monitor and control quality.
- (c) Sampling inspection: only one part of SQC, focused on accepting/rejecting lots, not the full set of techniques described.
- (d) None of these: incorrect because option (b) matches the description.
Which of the following is/are not included in examples of machine element that employ friction for transfer of energy
A)
Belts
B)
Brakes
C)
Clutches
D)
Fuel tank
Machine elements that employ friction for transfer of energy include belts, brakes, and clutches. Belts transmit power by friction between the belt and pulley, while brakes and clutches use friction to control or transmit motion. A fuel tank does not perform any friction-based energy transfer function, so it is not included.
Which of the following is not a precision grinder?
A)
Abrasive belt grinder
B)
Surface grinder
C)
Cylinder grinder
D)
Internal grinder
Precision grinders are machine tools used for accurate finishing operations with close tolerances. Surface grinder, cylinder grinder, and internal grinder are all precision grinders because they can produce high accuracy and fine surface finish on flat, cylindrical, and internal surfaces respectively. An abrasive belt grinder is generally used for rough grinding, finishing, or polishing, and is not classified as a precision grinder.
The specification for the shapes, sizes and finishes are furnished to the shop by part drawings or manufacturing drawings. These specifications are often called
A)
Quality characteristics
B)
Standard measurements
C)
Engineering drawings
D)
None of these
Part drawings or manufacturing drawings furnish the specifications of shape, size, and finish to the shop. Such drawings are commonly called engineering drawings because they communicate the technical details needed for manufacture. The other options do not correctly describe this standard term.
A process of joining similar metal by rivet is called
A)
Welding
B)
Balancing
C)
Rivetting
D)
None of these
Joining similar metal parts using a rivet is called riveting. A rivet is a permanent mechanical fastener used to join plates or sheets together. Welding joins metals by fusion, balancing is unrelated, and 'none of these' is incorrect.
A machine tool that removes metal as the work is fed against a rotating multipoint cutter is
A)
Grinding machine
B)
Boring machine
C)
Gear hobbing machine
D)
Milling machine
In a milling machine, the workpiece is fed against a rotating multipoint cutter, and metal is removed in the form of chips.
Why others are incorrect:
- Grinding machine: uses an abrasive wheel, not a multipoint cutter.
- Boring machine: used to enlarge existing holes with a single-point tool.
- Gear hobbing machine: specifically used for cutting gears with a hob, though it also uses a rotating cutter, the general machine tool described here is the milling machine.
In one operation of high speed steel, the operation should be carried out at
A)
900 to 1100°C
B)
1100 to 1360°C
C)
1300 to 1500°C
D)
None of these
High speed steel is used for cutting tools that retain hardness at elevated temperatures. In operation, it is generally used at red-hot cutting temperatures, roughly around 900 to 1100°C. This range is suitable for high-speed machining because HSS maintains sufficient hardness due to its high hot hardness. The higher ranges in options (b) and (c) are beyond the practical operating temperature for HSS and would cause excessive softening and tool failure.
A process of generating a gear by means of a cutter that revolves and cuts like a milling cutter is called
A)
Rack cutter process
B)
Gear hobbing
C)
Slotting
D)
None of these
In gear hobbing, a rotating cutter called a hob revolves continuously and cuts the gear teeth in a milling-like action. This is the standard process for generating gears by means of a cutter that revolves and cuts like a milling cutter.
- (a) Rack cutter process: uses a rack-type cutter, not a revolving hob.
- (c) Slotting: is a reciprocating machining process, not gear generation by a revolving cutter.
- (d) None of these: incorrect because gear hobbing matches the description exactly.
A metal cannot exist in the
A)
Gaseous state
B)
Liquid state
C)
Solid state
D)
None of these
Metals are generally found in the solid state at ordinary conditions, and some can also exist in the liquid state when melted. In basic material science, metals are not considered to exist in the gaseous state under normal conditions because metallic bonding is not retained as a stable bulk phase there. Therefore, the correct answer is gaseous state. Liquid and solid states are both possible for metals, so options (b) and (c) are incorrect.
Ican’t believe you fell........... his lies.
A)
for
B)
down
C)
off
D)
of
The correct phrasal verb is **'fall for'**, which means to be deceived by someone or to believe a lie. So, 'I can’t believe you fell for his lies' is correct. The other options do not fit this meaning: 'fell down' means collapsed or moved downward, 'fell off' means dropped from something or decreased, and 'fell of' is not correct English here.
When the cost goes up, customers buy less clothing.
A)
simple sentence
B)
complex sentence
C)
compound sentence
The sentence has one independent clause, "customers buy less clothing," and one dependent adverbial clause, "When the cost goes up." The word "when" introduces the subordinate clause, making the whole sentence a complex sentence. It is not a simple sentence because it has a subordinate clause, and it is not a compound sentence because there are no two independent clauses joined by a coordinating conjunction.
Mark kept his schedule open in case of emergencies. (Identify the clause of the underlined words)
A)
noun clause
B)
adverb clause
C)
adjective clause
D)
independent clause
The underlined phrase 'in case of emergencies' tells us the condition under which Mark kept his schedule open. A clause/phrase showing condition, reason, time, purpose, etc. works as an adverbial element. Here, it modifies the verb phrase 'kept his schedule open' by expressing condition. So it is an adverb clause. It is not a noun clause because it does not act as a subject or object, not an adjective clause because it does not describe a noun, and not an independent clause because it cannot stand alone as a complete sentence.
Protects (Opposite meaning)
A)
Defends
B)
Deprives
C)
Deserts
D)
Devises
"Protects" means guards or defends. The opposite is to abandon or leave unguarded, which matches "deserts."
Why others are wrong:
- (a) Defends = similar to protects, not opposite.
- (b) Deprives = means takes away, but not the direct antonym of protects.
- (d) Devises = means invents or plans, unrelated.
The moon is full; the stars are out.
A)
simple sentence
B)
complex sentence
C)
compound sentence
The sentence has two independent clauses: "The moon is full" and "the stars are out." They are joined by a semicolon, which works like a coordinating conjunction here. Since each clause can stand alone, the sentence is a compound sentence. It is not simple because it has more than one clause, and it is not complex because there is no subordinate clause.
The chief concern of the specialist lay in:
A)
The nature of the author’s illness
B)
Inhow much he could help the author
C)
Inhow much he could get out of the author
D)
In how quickly he could cure the author’s malady
The specialist’s chief concern is typically the speed of recovery or cure of the patient’s illness. Option (d) matches this idea most directly. Option (a) is too general, while (b) and (c) do not fit the normal meaning of a doctor's concern in a medical context.
Do not condemn the judgment of others because it differs from your own.
A)
Exclamatory
B)
Imperative
C)
Negative
D)
Assertive
The sentence gives a command/advice: "Do not condemn...". Such sentences are classified as imperative sentences. It is not exclamatory because it does not show sudden emotion, not negative simply because of the word "not" (the main function is a command), and not assertive because it is not making a statement of fact.
Iwas completely worn............... after our hike.
A)
onto
B)
up
C)
down
D)
out
The correct phrasal verb is "worn out," which means exhausted or extremely tired. So the sentence becomes: "I was completely worn out after our hike."
Why others are incorrect:
- "worn up" is not the correct idiom here.
- "worn down" means gradually weakened or defeated, but not the usual expression for being physically exhausted after exercise.
- "worn onto" is not a valid phrasal verb in this context.
He knew hehada............ chance of winning the election.
A)
good
B)
well
C)
better
D)
best
The correct phrase is "had a good chance of winning." Here, "chance" is a noun, so it is modified by the adjective "good". "Well" is an adverb, so it cannot correctly describe the noun "chance." "Better" and "best" are comparative and superlative forms, but this sentence does not require comparison.
He cannot live ina closed apartment. Heis.........
A)
Claustrophobic
B)
Congested
C)
Acrophobic
D)
Sensitive
A person who cannot live in a closed or confined apartment likely suffers from claustrophobia, which is fear or discomfort in enclosed spaces. So 'claustrophobic' fits best. 'Congested' means crowded, 'acrophobic' means fear of heights, and 'sensitive' does not match the context.
God is present everywhere. Heis.........
A)
Omniscient
B)
Omnipresent
C)
Omnipotent
D)
Convalescent
“God is present everywhere” means God exists in all places at the same time. The word for this is **omnipresent**.
- **Omniscient** = all-knowing
- **Omnipresent** = present everywhere
- **Omnipotent** = all-powerful
- **Convalescent** = recovering from illness
City life is starting to grow........... me.
A)
on
B)
for
C)
around
D)
without
The correct phrasal verb is "grow on me," which means to become more pleasant or appealing over time. So the sentence becomes: "City life is starting to grow on me." The other options do not form the correct idiomatic expression.
Eight hours of sleep is good for us as it ............. us.
A)
sensitizes
B)
enervates
C)
hallucinates
D)
energizes
The sentence means that eight hours of sleep is beneficial because it gives us energy. Among the options, "energizes" fits this meaning.
- sensitizes = makes someone more sensitive
- enervates = weakens or drains energy
- hallucinates = causes false perceptions
- energizes = gives energy, refreshes
So the correct answer is "energizes".
Feel under the weather
A)
feel unwanted
B)
angry
C)
feel sleepy
D)
feelill
"Feel under the weather" is an idiom meaning "to feel slightly ill or unwell." Among the options, "feel ill" matches this meaning best. The other options do not fit the idiom.
