21. Which of the following factors does NOT affect the magnitude of beam reactions?

1. Support conditions
2. Applied load
3. Material density
4. Beam length

Answer

The correct answer is: C) Material density

Explanation

Beam reactions are primarily influenced by external factors such as the applied load and support conditions. The length of the beam and the material density do not directly affect beam reactions.
