What role does the moment of inertia play in beam deflections?

48. What role does the moment of inertia play in beam deflections?

1. Determines material strength
2. Controls material density
3. Affects beam shape
4. Influences support conditions

Answer

The correct answer is: C) Affects beam shape

Explanation

A beam's resistance to bending is influenced by a geometric feature called the moment of inertia. Beam deflections are reduced with higher moment of inertia levels.
