Tension Members MCQs : This section focuses on the "Tension Members" in Steel Structures. These Multiple Choice Questions (MCQs) should be practiced to improve the Steel Structures skills required for various interviews (campus interview, walk-in interview, company interview), placement, entrance exam and other competitive examinations.
Question 1
Tension members are structural elements that are subjected to axial tensile forces.
A. TRUE
B. FALSE
C. Can be true or false
D. Can not say
View Answer
Ans : A
Explanation: True, Tension members are structural elements that are subjected to axial tensile forces.
Question 2
Examples of tension members are ?
A. bracing for buildings
B. bridges
C. truss members
D. All of the above
View Answer
Ans : D
Explanation: Examples of tension members are bracing for buildings and bridges, truss members, and cables in suspended roof systems.
Question 3
In an axially loaded tension member, the stress is given by?
A. F/A
B. P/A
C. F/P
D. A/P
View Answer
Ans : B
Explanation: In an axially loaded tension member, the stress is given by: F = P/A ; where P is the magnitude of the load and A is the cross-sectional area.
Question 4
The tension members made of structural steel can be broadly grouped into __________ categories.
A. 2
B. 3
C. 4
D. 5
View Answer
Ans : C
Explanation: The tension members made of structural steel can be broadly grouped into four categories:Wires and Cables, Bars and Rods, Single Structural Plates and Shapes and Built-up Sections.
Question 5
The strength of tensile members is not influenced by :
A. length of connection
B. net area of cross section
C. type of fabrication
D. length of plate
View Answer
Ans : D
Explanation: The strength of tensile members is influenced by factors such as length of connection, size and spacing of fasteners, size and spacing of fasteners, net area of cross section, type of fabrication, connection eccentricity, and shear lag at the end connection.
Question 6
What is the yield point for high strength steel?
A. 0.5% of offset load
B. 0.2% of offset load
C. 0.2% of offset load
D. 1.5% of offset load
View Answer
Ans : B
Explanation: High-strength steel tension members do not exhibit well defined yield point and yield plateau. Hence, 0.2% of offset load is usually taken as yield point for such high strength steel.
Question 7
Which of the following statement is correct?
A. Single angle members are used where members are subjected to reversal of stresses
B. Double angle members are used in towers
C. Single angle members are used as web members in trusses
D. Double angle members are used as web members in trusses
View Answer
Ans : C
Explanation: Single angle members are used in towers and as web members in trusses. Double angle sections are used as chord members in light roof trusses or in situations where some rigidity is required and where members are subjected to reversal of stresses.
Question 8
True stress strain curve is also known as
A. flow curve
B. un-flow curve
C. elastic curve
D. parabolic curve
View Answer
Ans : A
Explanation: True stress strain curve is also known as flow curve since it represents basic plastic flow characteristics if the material. Any point on the flow curve can be considered as local stress for metal strained in tension by magnitude shown on the curve.
Question 9
Bars and rods are not used as :
A. tension members in bracing systems
B. friction resistant members
C. sag rods to support purlin
D. to support girts in industrial buildings
View Answer
Ans : B
Explanation: Bars and rods are used as tension members in bracing systems, sag rods to support purlin between trusses, to support girts in industrial buildings, where light structure is desirable. Rods are also used in arches to resist thrust of arch.
Question 10
Is beam a tension member?
A. TRUE
B. FALSE
C. Can be true or false
D. Can not say
View Answer
Ans : A
Explanation: A beam is a horizontal structural member that spans some open space and is supported near the ends.
