This set of Structural Analysis Multiple Choice Questions & Answers (MCQs) focuses on “Method of Sections”.

1. How many equilibrium equations are used in method of sections?

a) 2

b) 4

c) 3

d) 5

View Answer

Explanation: Moments too can be conserved along with forces in both directions. So, total no. of equations are three.

2. In trusses, a member in the state of tension is subjected to:-

a) push

b) pull

c) lateral force

d) either pull or push

View Answer

Explanation: Pull is for tension, while push is for compression.

3. In method of sections, what is the maximum no. of unknown members through which the imaginary section can pass?

a) 1

b) 2

c) 3

d) 4

View Answer

Explanation: Since we have three equilibrium equations, so we can have maximum 3 unknown forces/members through which imaginary section can pass.

4. Method of substitute members is use for which type of trusses?

a) complex

b) compound

c) simple

d) simple and compound

View Answer

Explanation: Method of substitute members is used to solve problems involving complex trusses.

5. First step to solve complex truss using Method of substitute members is to convert it into unstable simple truss.

State whether the above statement is true or false.

a) true

b) false

View Answer

Explanation: First step is to convert it to stable simple truss.

Shear force is represented by V

Bending moment is represented by M

Distance along the truss is represented by X

W is the uniform load applied.

6. On differentiating V wrt X we will get:-

a) W

b) -W

c) M

d) None of the mentioned

View Answer

Explanation: On applying equilibrium equation, V – W(x)Δx – V – ΔV = 0.

7. On differentiating M wrt X we will get:-

a) W

b) -W

c) V

d) None of the mentioned

View Answer

Explanation: On applying equilibrium equation, M + VΔx – M – ΔM = 0.

8. If a member of a truss is in compression, then what will be the direction of force that it will apply to the joints?

a) Outward

b) Inward

c) Depends on case

d) No force will be there

View Answer

Explanation: Member will apply outward force. Joint will in turn apply inward force resulting in compression of the member.
