This set of Structural Analysis Multiple Choice Questions & Answers (MCQs) focuses on “Analysis of Beams-1”.

1. While using slope deflection method, in which direction is moment taken as positive?

a) Clockwise

b) Anti-clockwise

c) Depends upon case

d) Depends upon loading

View Answer

Explanation: Clockwise moments are always taken as positive while theses equations.

2. While drawing BMD after using these equations, in which direction is moment taken as positive?

a) Clockwise

b) Anti-clockwise

c) Depends upon case

d) Depends upon loading

View Answer

Explanation: While drawing BMD after using these equations we use our usual notations for sign of moments.

3. If support B settles by 1mm downward, what is direction of rotation at point A?

a) +ve

b) -ve

c) Can’t say

d) Depends upon loading at point A

View Answer

Explanation: In this case, AB rotates clockwise about point A, so rotation is +ve.

4 If support B settles by 1mm downward, what is direction of rotation at point B?

a) +ve

b) -ve

c) Can’t say

d) Depends upon loading at point A

View Answer

Explanation: In this case, AB rotates clockwise about point B, so rotation is +ve.

5. If support A settles by 1mm downward, what is direction of rotation at point A?

a) +ve

b) -ve

c) Can’t say

d) Depends upon loading at point A

View Answer

Explanation: In this case, AB rotates anti clockwise about point A, so rotation is +ve.

6. If support A settles by 1mm downward, what is direction of rotation at point B?

a) +ve

b) -ve

c) Can’t say

d) Depends upon loading at point A

View Answer

Explanation: In this case, AB rotates anti clockwise about point B, so rotation is +ve.

7. If a beam has 4 external supports, then how many parts would it be divided in case of using slope deflection equations?

a) 0

b) 1

c) 2

d) 3

View Answer

Explanation: We divide each part between two supports, so there will be 3 parts as 4 supports are there.

8. How many sde (slope deflection equations) are possible if 4 supports are there?

a) 0

b) 3

c) 4

d) 6

View Answer

Explanation: Each part will give 2 unique equations, so there will be a total of 6 equations.

9. Initially, how many total unknowns will be there in 6 equations?

a) 3

b) 6

c) 9

d) 12

View Answer

Explanation: Total 9 unknowns will be there, 2 rotations and one deflection in each part.

10. After writing sde, what is the second step?

a) Use stress-strain relationship

b) Use equilibrium equations

c) Use compatibility equations

d) Can’t say

View Answer

Explanation: After writing sde, we use equilibrium equations so as to lessen the no. of unknowns.
