A. axial tension
B. compression
C. Both A and B
D. None of the above
View Answer

A. Truss
B. Gussets
C. Purlin
D. Ridge tops
View Answer
Ans : A
Explanation: A truss is essentially a triangulated system of straight interconnected structural elements.
Question 3
Which of the following are main reasons for using trusses?
A. Long span
B. Lightweight
C. Reduced deflection
D. All of the above
View Answer
Ans : D
Explanation: The main reasons for using trusses are : Long span, Lightweight, Reduced deflection (compared to plain members) and Opportunity to support considerable loads.
Question 4
Trusses are widely used to serve ________ main functions?
A. 1
B. 2
C. 3
D. 4
View Answer
Ans : B
Explanation: Trusses are widely used to serve two main functions: To carry the roof load and To provide horizontal stability.
Question 5
Pratt trusses are commonly used in long span buildings ranging from?
A. 5 to 10 m
B. 15 to 50 m
C. 20 to 100 m
D. 100 to 500 m
View Answer
Ans : C
Explanation: Pratt trusses are commonly used in long span buildings ranging from 20 to 100 m in span.
Question 6
Which trusses are traditionally used for short spans in industrial workshop-type buildings?
A. North light
B. Saw-tooth truss
C. Fink truss
D. Pratt truss
View Answer
Ans : A
Explanation: North light trusses are traditionally used for short spans in industrial workshop-type buildings. They allow maximum benefit to be gained from natural lighting by the use of glazing on the steeper pitch which generally faces north or north-east to reduce solar gain.
Question 7
Trusses are subjected to ___________ stress.
A. Compressive
B. Tensile
C. Lateral
D. Direct
View Answer
Ans : D
Explanation: Trusses are the members which are subjected to direct stress, as the truss is usually loaded at the point of intersection of its member only.
Question 8
Trusses are adopted for ___________ span.
A. Medium
B. Short
C. Very Large
D. Large
View Answer
Ans : C
Explanation: Trusses are useful at the places of high rainfall to avoid roof drainage problems. For very large span the use of beams will make the construction most uneconomical.
Question 9
The top line of roof truss is called as ___________
A. Ridge Line
B. Pitch
C. Main Tie
D. Eves
View Answer
Ans : A
Explanation: The top line of the roof truss is called “ridge line”. The bottom edge of roof surface is called a ridge line. Corrugated galvanised iron (GI) or asbestos cement (AC) sheets are commonly used for roof covering.
Question 10
The Fink truss offers economy in terms of steel weight for short-span high-pitched roofs as the members are subdivided into shorter elements
A. TRUE
B. FALSE
C. Can be true or false
D. Can not say
View Answer
Ans : A
Explanation: The Fink truss offers economy in terms of steel weight for short-span high-pitched roofs as the members are subdivided into shorter elements
