Past Questions
The maximum permissible variation in the size of the part is
A)
Basic dimensions
B)
Tolerance
C)
Clearance
D)
None of these
The maximum permissible variation in the size of a part from its basic size is called **tolerance**. It defines the allowed upper and lower limits of size during manufacturing.
- **Basic dimension** is the nominal or theoretical size, not the permitted variation.
- **Clearance** is the intentional gap between mating parts, not the variation itself.
- Therefore, the correct answer is **tolerance**.
The basic philosophy of quality control is
A)
Frequent inspection
B)
Both preventive & remedial
C)
Only preventive
D)
None of these
Quality control is not limited to checking finished output. Its basic philosophy is to prevent defects by controlling the process and also to correct defects when they are found. Therefore, it combines both preventive and remedial actions. Option (a) is too narrow, (c) is incomplete because QC is not only preventive, and (d) is incorrect because option (b) is the right choice.
Which transmission unit disengages the drive and provides a smooth take up the drive?
A)
Final drive
B)
Differential
C)
Clutch
D)
Gearbox
The clutch is the transmission unit that temporarily disconnects the engine from the gearbox, thereby disengaging the drive. It also allows the drive to be taken up smoothly when power transmission is restored. The final drive and differential mainly transmit and distribute power to the wheels, while the gearbox changes speed/torque ratios.
Which of the following does not form part of belts?
A)
Flat belt
B)
Chain
C)
Belt
D)
V-Belt
Belts in machine elements include flat belts, V-belts, and other belt types used for power transmission. A chain is not a belt; it belongs to chain drive systems. Therefore, the option that does not form part of belts is Chain.
The method of measuring and/or checking the quality of a product in terms of specified standard
A)
Manufacturing
B)
Material handling
C)
Inspection
D)
None of these
Inspection means measuring, examining, and/or checking a product’s quality against specified standards. It is used to see whether the product meets the required specifications. Manufacturing is the production process, and material handling is concerned with movement/storage of materials, so neither matches the definition.
Which of the following is not part of major factors of production?
A)
Land
B)
Labour & Capital
C)
Machinery
D)
None of these
The major factors of production are traditionally land, labour, capital, and enterprise/organization. 'Machinery' is not a separate major factor; it is a part of capital. Therefore, among the given options, Machinery is not part of the major factors of production. Land is a factor, Labour & Capital are factors, so 'None of these' is incorrect.
What type of annealing consists of - heating the steel slightly above the critical point, holding it at that temperature for a considerable period & slowly cooling?
A)
Spheroidise annealing
B)
Process annealing
C)
Full annealing
D)
None of these
Full annealing involves heating steel slightly above its critical point, holding it there for some time, and then cooling it slowly, usually in the furnace. This produces a soft, ductile structure. Spheroidise annealing is used mainly for high-carbon steel to form spheroidized cementite, while process annealing is done below the critical point to relieve stresses in low-carbon steel.
Which is not one of the principal parts of a Column & Knee type of milling machine?
A)
Piston ring
B)
Knee
C)
Base
D)
Column
A column-and-knee type milling machine has principal parts such as the base, column, knee, saddle, table, overarm, and spindle. The piston ring is an engine component, not a milling machine part. Therefore, it is the option that is not one of the principal parts.
Any member of a structure which is in compression may be called
A)
A column
B)
A truss
C)
A strut
D)
None of these
A structural member that carries compressive force is generally called a strut. In strength of materials, a strut is any member subjected to axial compression. A column is also a compression member, but the broader and more general term for any compressed member is strut. A truss is an assembly of members, not a single compressive member. Therefore, the correct answer is A strut.
A method of uniting two or more pieces of metal by means of a fusible alloy or metal, applied in the molten state is
A)
Welding
B)
Soldering
C)
Balancing
D)
None of these
The process described is soldering: two or more metal pieces are joined using a fusible alloy/metal (solder) applied in the molten state. Welding joins metals by fusion of the base metals themselves, not by a lower-melting filler alone. Balancing is unrelated.
Which is not one of principal parts of capstan & turret lathe?
A)
Hexagonal turret
B)
Headstock
C)
Lathe bed
D)
Knee
A capstan and turret lathe has principal parts such as the headstock, lathe bed, and turret/hexagonal turret. The knee is a part of a milling machine, not a lathe. Therefore, it is not one of the principal parts of a capstan and turret lathe.
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.
The power (in horse power) transmitted by a belt drive is (T1 = belt tension in tight side, T2 = belt tension in loose side and V = belt speed)
A)
Power = (T1-T2)V
B)
Power = (T1+T2)V
C)
Power = T1V
D)
None of these
In a belt drive, the effective driving force is the difference between the tight-side tension and the loose-side tension, i.e. (T1 - T2). Power transmitted equals force × velocity, so P = (T1 - T2)V. Hence option (a) is correct. Option (b) uses the sum of tensions, which is not the net driving force, and option (c) ignores the loose-side tension, so both are incorrect.
What is a prime consideration in designing the new plant building?
A)
Material handling
B)
Drawings
C)
Machine loading
D)
Value engineering
In industrial engineering, a prime consideration in designing a new plant building is efficient material handling, because the building layout must support smooth movement of materials, reduce travel distance, and minimize delays and handling cost. Drawings are only a planning document, machine loading is a scheduling concern, and value engineering is a cost-reduction technique rather than the primary design consideration for the building itself.
The ratio of the direct stress to the strain produced is called
A)
Shear modulus
B)
Rigidity
C)
Young’s modulus
D)
None of these
Direct stress divided by the corresponding strain gives the modulus of elasticity in tension or compression, which is called Young’s modulus. Shear modulus relates shear stress to shear strain, and rigidity is another term associated with resistance to shear, not direct stress-strain ratio.
Manipulate
A)
Display
B)
Gloomy
C)
To handle or manage
D)
To mortgage
“Manipulate” means to handle, control, or manage something skillfully. Among the options, (c) gives the correct synonym. (a) Display means to show, (b) Gloomy means sad or dark, and (d) To mortgage means to pledge property for a loan, so they are not synonyms.
Inthe shopping mall, I met a friend I hadn’t seen for years.
A)
Exclamatory
B)
Imperative
C)
Negative
D)
Assertive
The sentence is a simple statement of fact: 'In the shopping mall, I met a friend I hadn’t seen for years.' Such sentences are called assertive (declarative) sentences. It is not exclamatory because it does not express strong emotion, not imperative because it gives no command or request, and not negative in structure even though it contains 'hadn’t' inside the relative clause.
Spina yarn
A)
to tella fanciful story
B)
to be talented
C)
tobe watchful
D)
to be old fashioned
The idiom appears to be a misspelling of "spin a yarn," which means to tell a long, imaginary, or fanciful story. So option (a) is correct. The other options do not match the meaning of the idiom.
A professional should be
A)
asycophant
B)
solely concerned with profits
C)
courteous and humble
D)
competitive
A professional is expected to behave with good manners, respect, and modesty. 'Courteous and humble' best fits this ideal. The other options are inappropriate: (a) 'asycophant' is misspelled and means a flatterer, which is not a professional quality; (b) being solely concerned with profits is too narrow and unethical; (d) being competitive may be useful, but it is not the defining moral quality asked here.
Jack spoke.............. to the audience urging them to elect him.
A)
confident
B)
confidently
C)
confidence
D)
confidant
The blank modifies the verb "spoke", so an adverb is needed. "Confidently" is the correct adverb form of "confident".
- "confident" is an adjective, not suitable here.
- "confidence" is a noun.
- "confidant" means a trusted person, which is unrelated.
Therefore, "Jack spoke confidently to the audience..." is correct.
To sell someone out
A)
to bea good salesman
B)
to be misunderstood
C)
to betray someone
D)
to misunderstand
"To sell someone out" is an idiom meaning to betray someone or reveal their secrets, often for personal gain. Option (c) matches this meaning. The other options do not express betrayal: (a) refers to sales skill, (b) means to be misunderstood, and (d) means to misunderstand.
Which amongst the below mentioned is not one of the seven golden rules for better health?
A)
Getting eight hours sleep nightly
B)
Eating regularly and not between meals
C)
Drinking alcoholic beverages
D)
Not smoking or drinking
The seven golden rules for better health include healthy habits such as adequate sleep, regular eating, and avoiding smoking and alcohol. Among the options, 'Drinking alcoholic beverages' is not a golden rule; it is contrary to better health. The other options are consistent with healthy living guidelines.
He wasn’t strong enough to lift his heavy bag. (Identify part of speech of 'heavy')
A)
Noun
B)
Adverb
C)
Adjective
'Heavy' describes the noun 'bag', so it functions as an adjective. A noun names a person, place, thing, or idea; an adverb modifies a verb, adjective, or another adverb; but here 'heavy' is modifying 'bag'. Therefore, the correct answer is Adjective.
Deteriorate
A)
Appreciate
B)
Recover
C)
To make worse
D)
Strengthen
"Deteriorate" means to become worse or to make something worse in condition, quality, or state. Among the options, "To make worse" is the closest synonym. "Appreciate" means value or rise in worth, "Recover" means get better, and "Strengthen" means make stronger, so they are incorrect.
Fruit that is grown organically is expensive. (Identify the clause of the underlined words)
A)
noun clause
B)
adverb clause
C)
adjective clause
D)
independent clause
The underlined words likely refer to the clause "that is grown organically," which modifies the noun "fruit." A clause that describes or qualifies a noun is an adjective clause (relative clause). It answers the question: which fruit? — the fruit that is grown organically. It is not an adverb clause because it does not modify a verb, and it is not a noun clause because it does not function as a noun. It is also not independent because it cannot stand alone as a complete sentence.
