Structural Analysis Questions and Answers – Internal Loadings at a Specified Point-2

This set of Structural Analysis Questions and Answers for Experienced people focuses on “Internal Loadings at a Specified Point-2”.

We have followed following sign convention in our questions.
The internal force in y direction at joint B is 30

Following sign convention for force direction is followed:-
The part between points B & C & balance the force along y direction

In the following figure, point A has pin support, while point C has roller type support. Point B is a fixed end.
Following figure has been used in Q1-Q3.
All the options are given in KN and KN/M wherever applicable.
AB = 4m and BC = 8m.
The point A has pin support, while point C has roller type support

1. What will be the internal force in y direction at joint B?
a) 10
b) 20
c) 30
d) 40
View Answer

Answer: c
Explanation: Separate out the part between points B and C and balance the force along y direction.

2. What will be the internal force in x direction at joint B?
a) 0
b) 20
c) 30
d) 40
View Answer

Answer: a
Explanation: Separate out the part between points B and C and balance the force along x direction.

3. What will be the internal moment generated at joint B due to above shown loading?
a) 80
b) 120
c) 240
d) 160
View Answer

Answer: c
Explanation: It can be found out by balancing moment about point B in the part between points B and C.

Following figure has been used in Q4-Q9.
In the following figure AB=BC=CD=2m, and DE=EF=1m.
A is a fixed support while C and F are of roller type. B and D are hinges.
All the options are given in KN and KN/M wherever applicable.
BMD and SFD starts from point A.
The internal force generated at hinge D due to the above loading is 15

4. What will be the internal force generated at hinge D due to the above loading?
a) 5
b) 10
c) 15
d) 20
View Answer

Answer: c
Explanation: We will cut out the first part from point D to F (Since, D is a hinge). Now balancing moment about point F, internal force will come out to be 15KN.

5. What will be the internal force generated at hinge B due to the above loading?
a) 5
b) 10
c) 15
d) 20
View Answer

Answer: c
Explanation: We can separate the part from point B to D. Now, we have internal load at D so, we can balance moment about point C and find out the force at point B.

6. What will be the support force due to point C?
a) 15
b) 20
c) 25
d) 30
View Answer

Answer: d
Explanation: This can be found out by balancing force in the part between both the hinges.

7. What will be the support reaction generated by support A?
a) 25
b) 10
c) 15
d) 20
View Answer

Answer: a
Explanation: This can be found out by balancing force in the part between joints A and B.

8. What will be the support reaction generated by support F?
a) 5
b) 7.5
c) 10
d) 15
View Answer

Answer: d
Explanation: This can be found out by balancing force between points D and F.

9. What will be moment generated by support A?
a) 5
b) 7.5
c) 10
d) 12.5
View Answer

Answer: c
Explanation: This can be found out by balancing moment between points A and C.
