Match the following lists :
| List-I (Types of beams with) | List-II (Applications) |
|---|---|
| P.Angles | 1.Long spans and heavy loads |
| Q.Rolled I-sections | 2.Roof purlin and sheeting rail |
| R.Castellated beams | 3.Most frequently used as a beam |
| S.Plate girders | 4.Long spans and light loads |
Select the correct answer using the code given below :
- A3 4 1 2
- B3 1 4 2
- C2 3 4 1Correct
- D2 4 1 3
Solution
Concept
Applications of steel beam sections
Step-by-step solution
1. Angles are used as roof purlins and sheeting rails → 2. 2. Rolled I-sections are the most common beam → 3. 3. Castellated beams give long spans for light loads → 4. 4. Plate girders carry heavy loads over long spans → 1.
Explanation
Each type of beam is chosen for its capacity and economy.
Why the other options are wrong
The other codes give plate girders light loads or castellated beams heavy loads.
Shortcut
Plate girder = heavy, long; castellated = light, long.
Correct answer: C) 2 3 4 1
