1. What is Simply Supported Beam?

A simply supported beam is a structural element that rests on two supports at its ends and is free to rotate at these supports. When a center point load is applied, the reaction forces at both supports are equal and each is half of the total load.

2. How Does the Calculator Work?

The calculator uses the simply supported beam formula:

Where:

• \( R \) — Reaction force at each support (N)
• \( P \) — Total applied load at center (N)

Explanation: For a simply supported beam with a center point load, the load is equally distributed between the two supports, resulting in each support carrying half of the total load.

3. Importance of Reaction Force Calculation

Details: Calculating reaction forces is essential for structural analysis and design. It helps determine the load distribution on supports and ensures the structural integrity of the beam and its supporting elements.

4. Using the Calculator

Tips: Enter the total load applied at the center of the beam in Newtons (N). The value must be positive and greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is a simply supported beam?
A: A simply supported beam is a beam supported on both ends that is free to rotate at the supports without any moment resistance.

Q2: Why are the reaction forces equal?
A: For a symmetrically loaded beam (center point load), the load is equally distributed between the two supports due to symmetry.

Q3: What if the load is not at the center?
A: If the load is not at the center, the reaction forces will not be equal. Different formulas would be needed to calculate the reaction forces at each support.

Q4: What units should I use?
A: The calculator uses Newtons (N) for both input and output. Ensure consistent units for accurate results.

Q5: Can this calculator handle multiple loads?
A: No, this calculator is designed specifically for a single center point load. For multiple loads, more complex analysis is required.
