1. What is Stress of Beam of Uniform Strength?

Stress of Beam is the force per unit area applied to the material. The maximum stress a material can stand before it breaks is called the breaking stress or ultimate tensile stress.

2. How Does the Calculator Work?

The calculator uses the Stress of Beam formula:

\[ \sigma = \frac{3 \cdot P \cdot a}{B \cdot d_e^2} \]

Where:

\( \sigma \) — Stress of Beam (Pascal)
\( P \) — Point Load (Newton)
\( a \) — Distance from A end (Meter)
\( B \) — Width of Beam Section (Meter)
\( d_e \) — Effective Depth of Beam (Meter)

Explanation: This formula calculates the stress in a beam under a point load, considering the beam's dimensions and the load position.

3. Importance of Stress Calculation

Details: Accurate stress calculation is crucial for structural design, ensuring beams can withstand applied loads without failure, and for determining safety factors in engineering applications.

4. Using the Calculator

Tips: Enter point load in Newtons, distances in meters. All values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is a point load?
A: Point Load is the instantaneous load applied perpendicular to the specimen cross section.

Q2: How is effective depth defined?
A: The effective depth of beam measured from compressive face of beam to centroid of tensile reinforcing.

Q3: What units should be used for input values?
A: Use Newtons for load, meters for all distance measurements, and Pascals for the resulting stress.

Q4: When is this formula applicable?
A: This formula is specifically for calculating stress in beams of uniform strength under point loading conditions.

Q5: What are typical stress values for common materials?
A: Stress values vary significantly by material. Steel typically has ultimate tensile strength around 400-550 MPa, while concrete is around 20-40 MPa in compression.
