What factor primarily influences beam deflections in structural analysis?

45. What factor primarily influences beam deflections in structural analysis?

1. Beam length
2. Material density
3. Temperature changes
4. Shear forces

Answer

The correct answer is: A) Beam length

Explanation

Beam deflections are directly proportional to the length of the beam. Longer beams experience larger deflections under the same load compared to shorter beams.
