1. What is the Inner Length of Frame?

The Inner Length of Frame is the length or longest side of the inner rectangle of the Frame. It represents the internal dimension of the frame structure.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( l_{Inner} \) — Inner Length of Frame (m)
• \( w_{Outer} \) — Outer Width of Frame (m)
• \( l_{Outer} \) — Outer Length of Frame (m)
• \( A \) — Area of Frame (m²)
• \( w_{Inner} \) — Inner Width of Frame (m)

Explanation: This formula calculates the inner length by subtracting the frame area from the outer rectangle area and dividing by the inner width.

3. Importance of Frame Calculations

Details: Accurate frame dimension calculations are crucial for architectural design, construction planning, and material estimation in framing projects.

4. Using the Calculator

Tips: Enter all dimensions in meters and area in square meters. Ensure all values are positive numbers with appropriate decimal precision.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for input values?
A: All length measurements should be in meters (m) and area in square meters (m²) for consistent results.

Q2: Can this calculator handle decimal inputs?
A: Yes, the calculator accepts decimal values with up to 4 decimal places for precise calculations.

Q3: What if I get a negative result?
A: A negative result indicates that the input values may be inconsistent or the frame area exceeds the outer rectangle area.

Q4: Is this formula applicable to all frame types?
A: This formula works for rectangular frames where the inner and outer rectangles are concentric and parallel.

Q5: How accurate are the results?
A: The results are mathematically precise based on the input values, with rounding to 6 decimal places for clarity.
