Question

Strength of beam is directly proportional to its
1) Length
2) Depth
3) Width
4) Moment of Inertia

Answer 1

Strength of beam is directly proportional to its Width...

Answer 2

Answer:

Width

Explanation:

Given the strength of the beam as S the strength S of the beam will be proportional to:

1) The width of the beam.

2) The square of the depth of the beam.

However the Strength S of the beam is inversely proportional to its length.

The correct answer from the given choices is thus :

3 — Width
