1. What is Shear Force Calculation for Beam?

Definition: This calculator determines the shear force in a beam based on the distributed load and beam length.

Purpose: It helps structural engineers and designers analyze beam behavior under various loading conditions.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V \) — Shear force (Newtons, N)
• \( w \) — Distributed load (Newtons per meter, N/m)
• \( dx \) — Length element (meters, m)

Explanation: For uniform loads, the shear force is calculated by multiplying the load intensity by the beam length.

3. Importance of Shear Force Calculation

Details: Proper shear force calculation ensures beam safety, prevents structural failures, and helps in proper reinforcement design.

4. Using the Calculator

Tips: Enter the distributed load in N/m and beam length in meters. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is shear force in beams?
A: Shear force is the internal force perpendicular to the beam's longitudinal axis caused by external loads.

Q2: What's a typical distributed load value?
A: This varies greatly depending on application - from 100 N/m for light structures to 10,000+ N/m for heavy industrial beams.

Q3: How does this differ for point loads?
A: For point loads, the shear force changes abruptly at the load point rather than varying continuously.

Q4: What about non-uniform loads?
A: For varying loads, integration would consider the load as a function of position along the beam.

Q5: How is this related to bending moment?
A: The shear force is the derivative of the bending moment with respect to beam length.
