The depth of footing for an isolated column is governed by: 1) Maximum bending moment, 2) Shear Force, 3) Punching Shear; The Correct answer is :
A)
Only (1)
B)
Both (1) and (2)
C)
Both (1) and (3)
D)
All (1), (2) and (3)
For an isolated footing, the depth (effective depth/thickness) is selected to safely resist all critical structural actions: (1) bending moment, (2) one-way shear, and (3) punching shear. The footing must be thick enough so that flexural strength and both shear checks are satisfied. Therefore, all three govern the footing depth.
In a well-seasoned timber, the moisture content will be in the range of
A)
20-25%
B)
15-20%
C)
10-12%
D)
5-7%
Well-seasoned timber is timber that has been dried sufficiently for use, and its moisture content is typically reduced to about 10–12%. This range gives good strength, durability, and dimensional stability. Higher moisture contents like 15–25% indicate less seasoning, while 5–7% is unusually low for ordinary well-seasoned timber.
The Young’s Modulus of elasticity of steel is
A)
150 kN/mm2
B)
200 kN/mm2
C)
250 kN/mm2
D)
300 kN/mm2
Young’s modulus of elasticity for steel is commonly taken as about 200 GPa, which is equal to 200 kN/mm². Hence option (b) is correct. The other values are not the standard modulus for steel.
The path traced by a projectile in the sky is
A)
circular
B)
parabolic
C)
elliptical
D)
catenary
For ideal projectile motion (neglecting air resistance), the horizontal motion is uniform and the vertical motion is uniformly accelerated due to gravity. Combining these two motions gives a parabolic trajectory. Hence, the path traced by a projectile is parabolic. Circular, elliptical, and catenary paths do not describe standard projectile motion.
The type of window provided on the sloping side of a pitched roof is called
A)
Gable window
B)
Dormer window
C)
Lantern
D)
None of these
A window provided on the sloping side of a pitched roof is called a dormer window. It projects from the roof slope to admit light and ventilation. A gable window is located in the gable end wall, while a lantern is a raised structure on the roof used mainly for light and ventilation.
The thickness at the edge of a reinforced concrete footing resting on soil shall not be less than
A)
25 cm
B)
20 cm
C)
15 cm
D)
10 cm
For reinforced concrete footings resting on soil, standard RCC design provisions specify that the thickness at the edge should not be less than 15 cm. This ensures adequate structural integrity, durability, and resistance to cracking at the footing edge. Hence, option (c) is correct. The other options are either too small for safe detailing or not the code-prescribed minimum.
A body will be in equilibrium when
A)
the algebraic sum of vertical components of all forces is zero
B)
the algebraic sum of horizontal components of all forces is zero
C)
the algebraic sum of moments components of all forces is zero
D)
all of these
For a body to be in equilibrium, the resultant force in every direction must be zero and the resultant moment must also be zero. Thus, the algebraic sum of vertical components of all forces is zero, the algebraic sum of horizontal components of all forces is zero, and the algebraic sum of moments of all forces is zero. Therefore, the correct answer is 'all of these'.
When an end of a continuous beam is fixed, in Kani’s method, the rotation contribution will be
A)
zero
B)
EI/l
C)
2EI/l
D)
4EI/l
In Kani’s method, a fixed end cannot rotate, so the rotation contribution at a fixed end is zero. Hence the correct option is (a) zero. The other values like EI/L, 2EI/L, or 4EI/L relate to member stiffness factors or distribution concepts, not the rotation contribution of a fixed support.
The type of organization suitable for paper industry is
A)
functional organization
B)
line organization
C)
line and staff organization
D)
none of these
Paper industry is a large-scale, complex manufacturing enterprise requiring both clear authority flow and specialist advice. A line and staff organization is suitable because the line managers handle production and control, while staff experts provide technical support, planning, and coordination. Functional organization is less suitable for overall industrial management, and pure line organization is too simple for a complex industry like paper manufacturing.
Margin of safety is generally expressed as
A)
ratio of budgeted sales to sales at BEP
B)
ratio of actual sales to sales at BEP
C)
percentage of budget to BEP
D)
all of these
Margin of safety is the excess of actual sales over break-even sales. In ratio form, it is generally expressed as actual sales divided by sales at break-even point (BEP), or as a percentage of actual sales. Option (a) is not the standard expression, and (c) is incorrect. Therefore, the correct answer is (b).
The basic drive systems usually used in commercially available robots is
A)
hydraulic
B)
electric motor
C)
pneumatic
D)
all the above
Commercially available robots usually use electric motors as the basic drive system because they are compact, efficient, easy to control, and suitable for precise motion. Hydraulic drives are used mainly where very high force is needed, and pneumatic drives are simpler but less precise. Therefore, the correct answer is electric motor.
Detailed work factor analysis under work study finds its wide application in
A)
electronic industry
B)
steel industry
C)
IT industry
D)
automobile industry
Work factor analysis is a motion study technique used to analyze manual work into basic motions and assign standard times. It is especially useful where jobs are repetitive, involve many short-cycle assembly operations, and require detailed motion-level study. This is why it finds wide application in the automobile industry. The other options are less suitable: electronic and steel industries use work study too, but the classic and widest application of detailed work factor analysis is in automobile manufacturing and assembly lines.
The type of production system suitable for zero inventories is named as
A)
CIM
B)
FMS
C)
CANBAN
D)
JIT
Zero inventories are the goal of Just-In-Time (JIT) production, where materials are supplied only when needed, minimizing or eliminating stock. CIM (Computer Integrated Manufacturing) is a broader automation concept, FMS (Flexible Manufacturing System) focuses on flexibility, and Kanban is a scheduling/control tool used within JIT, not the production system itself.
In full annealing, the hypereutectoid steel is heated from 30ºC to 50ºC above the upper critical temperature and then cooled in the furnace
A)
slowly
B)
rapidly
C)
first slowly then suddenly
D)
none of the above
In full annealing, steel is heated above the upper critical temperature and then cooled very slowly in the furnace. For hypereutectoid steel, this slow furnace cooling allows the structure to transform into soft, coarse pearlite with proeutectoid cementite, improving machinability and ductility. Rapid cooling would instead harden the steel, so option (b) is incorrect. Option (c) is not the standard annealing cooling method.
Multiple activity chart is used to optimize
A)
idle time
B)
work distribution
C)
labour cost
D)
all of these
A multiple activity chart is a work-study tool used to analyze the activities of two or more resources simultaneously, such as men and machines. Its purpose is to reduce idle time, improve work distribution, and thereby lower labour cost through better utilization of resources. Hence, it optimizes all of these.
Centre of gravity method is used in decision analysis of
A)
plant layout
B)
plant location
C)
plant floor
D)
plant area
The centre of gravity method is a quantitative technique used in facility location decisions to determine the best location for a plant, warehouse, or distribution center by minimizing transportation cost based on demand points and distances. It is not a plant layout method. Therefore, the correct answer is plant location.
The hardness is the property of the material due to which it can
A)
be drawn into wires
B)
be rolled into thin sheets
C)
resist fracture due to impact load
D)
cut another material
Hardness is the property of a material by which it resists indentation, scratching, and abrasion. A hard material can therefore cut another softer material. Option (a) refers to ductility, option (b) refers to malleability, and option (c) refers to toughness or impact resistance.
Due to simplification, the inventory stock becomes
A)
more
B)
less
C)
same
D)
none of these
In production management, simplification of products/processes reduces the variety of items, parts, and materials to be stored. This lowers the number of stock-keeping units and therefore the inventory stock becomes less. Hence, option (b) is correct.
In order to achieve part interchangeability, the type of layout suggested is
A)
product layout
B)
process layout
C)
combined layout
D)
matrix layout
Part interchangeability is best achieved when identical products are made in a fixed sequence with standardized operations and close control of dimensions. This is the feature of a product layout (also called line layout). In a product layout, machines are arranged according to the sequence of operations, which helps maintain uniformity and interchangeability of parts. A process layout groups similar machines together and is more flexible, so it is less suitable for interchangeability. Combined layout and matrix layout are not the standard layouts used for this purpose.
The iron that exists between 910ºC and 1405ºC is termed as
A)
α-iron
B)
β-iron
C)
γ-iron
D)
δ-iron
Iron exists in different allotropic forms at different temperature ranges. Between about 910°C and 1405°C, iron is in the gamma form, called γ-iron or austenite. α-iron exists below 910°C, and δ-iron exists above about 1405°C up to the melting point. Therefore, the correct answer is γ-iron.
Hematite iron ore contains about _______ of iron
A)
70%
B)
55%
C)
45%
D)
35%
Hematite is the chief iron ore and typically contains about 70% iron (more precisely around 69.9% Fe in pure hematite, Fe2O3). Therefore option (a) is correct. The other options are too low for hematite.
The type of organization which is not suitable for complex and large organization is
A)
functional organization
B)
line organization
C)
line and staff organization
D)
none of these
A line organization has a simple, direct chain of command and works well for small and simple setups. It is not suitable for complex and large organizations because coordination becomes difficult and top managers get overburdened. Functional and line-and-staff organizations are better suited for larger and more complex organizations because they provide specialization and advisory support.
Micro-structure of a material is generally examined by
A)
optical microscope
B)
X-ray technique
C)
spectroscope
D)
none of the above
Micro-structure refers to the internal structure of a material at microscopic scale, such as grains, phases, and defects. It is generally examined using an optical microscope after proper specimen preparation and etching. X-ray techniques are mainly used for crystal structure and phase analysis, while a spectroscope is used for studying spectra, not microstructure.
The aluminium alloy that is mainly used for anodized utensil manufacture is named as
A)
duralumin
B)
Y-alloy
C)
magnalium
D)
hindalium
Hindalium is an aluminium alloy commonly used for making anodized utensils because it has good corrosion resistance, is suitable for anodizing, and is widely used in cookware. Duralumin is mainly used for aircraft structures, Y-alloy is used in pistons and high-temperature applications, and magnalium is used for light instrument parts and in pyrotechnics, not primarily for anodized utensils.
At or above Curie temperature a ferromagnetic material behaves like a
A)
diamagnetic material
B)
paramagnetic material
C)
ferri magnetic material
D)
anti ferro magnetic materials
A ferromagnetic material loses its spontaneous magnetization at or above the Curie temperature. Above this temperature, thermal agitation randomizes the magnetic domains, so the material no longer shows ferromagnetism and behaves like a paramagnetic material. Hence, option (b) is correct. Diamagnetic, ferrimagnetic, and antiferromagnetic behaviors are not the standard behavior of a ferromagnet above Curie temperature.
