Match the following lists :
| List-I (Basic structural elements) | List-II (Applications) |
|---|---|
| P.Tin rods (tie rods) | 1.Carry tensile and compressive loads |
| Q.Beams | 2.Members that resist axial compressive force |
| R.Columns | 3.Bracing |
| S.Trusses | 4.Reinforced concrete |
Select the correct answer using the code given below :
- A2 3 4 1
- B3 4 2 1Correct
- C4 1 2 3
- D1 2 3 4
Solution
Concept
Basic structural elements
Step-by-step solution
1. Tie rods are used for bracing → 3. 2. Beams are commonly made of reinforced concrete → 4. 3. Columns resist axial compression → 2. 4. Trusses carry tension and compression in their members → 1.
Explanation
Each element is matched with its principal role in a structure.
Why the other options are wrong
The other codes assign compression-only roles to ties.
Shortcut
Tie = tension/bracing; column = compression; truss = both.
Correct answer: B) 3 4 2 1
