What role does the moment of inertia play in beam deflections?
48. What role does the moment of inertia play in beam deflections?
- Determines material strength
- Controls material density
- Affects beam shape
- 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.
