Several properties define the performance of this beam:

Weight (1200 N): This affects the beam’s self-loading and how much additional load it can support.
Length (3.5 m): Influences the beam’s bending moment and deflection under load.
Material: Determines the beam’s strength, stiffness, and resistance to environmental factors. Common materials include steel, aluminum, and wood.
Cross-Sectional Shape: Affects the beam’s moment of inertia, which is a measure of its resistance to bending. Common shapes include rectangular, I-beam, and circular.
Support Conditions: The way the beam is supported (e.g., simply supported, fixed at both ends) greatly affects its load-bearing capacity and deflection.

Understanding these properties allows engineers to accurately predict the beam’s performance and select the most appropriate beam for a given application.

3. What Materials Are Commonly Used for Uniform Beams?

Selecting the right material is crucial for the performance and longevity of a uniform beam. Which materials are typically used, and what are their advantages and disadvantages?

The choice of material depends on the specific requirements of the application:
