a) near main diagonal
b) near edges
c) in between
d) near side middles
View Answer

6. For computational purposes, deflected primary structure ans actual structure should be ___________
a) as different as possible
b) as similar as possible
c) it doesn’t matter
d) in between
View Answer

Answer: b
Explanation: This leads to small corrections induced by redundants.

7. Indeterminate analysis of a symmetrical structure is difficult from that of a non symmetric one.
State whether the above statement is true or false.
a) true
b) false
View Answer

Answer: b
Explanation: Symmetricity makes the indeterminate analysis easier.

8. In general, any structure can be classified as a symmetric one :-
a) when its structure is symmetric
b) when its loading is symmetric
c) when its supports are symmetric
d) when it develops symmetric internal loading and deflections
View Answer

Answer: d
Explanation: It is deemed as symmetric when when it develops symmetric internal loading and deflections about central axis.

9. Normally, which of the following things may/may not be symmetric to develop symmetricity?
a) material
b) geometry
c) loading
d) dki
View Answer

Answer: d
Explanation: Composition, geometry and loading are generally require to be symmetric.

10. Indeterminate analysis of a anti-symmetrically loaded structure is difficult from that of non symmetric one.
State whether the above statement is true or false.
a) true
b) false
View Answer

Answer: b
Explanation: Solving one side would give modulus of deflections of other side as well.
