1. What is the Tree Trunk Weight Formula?

The tree trunk weight formula calculates the mass of a cylindrical tree trunk based on its dimensions and wood density. It's essential for forestry, logging, and transportation planning.

2. How Does the Calculator Work?

The calculator uses the cylindrical volume formula:

Where:

• \( r \) — Radius of the tree trunk (meters)
• \( Length \) — Length of the trunk segment (meters)
• \( Density \) — Wood density (kg/m³)

Explanation: The formula calculates the volume of the cylindrical trunk and multiplies it by the wood density to get mass.

3. Importance of Weight Calculation

Details: Accurate weight estimation is crucial for transportation logistics, structural calculations, and commercial valuation of timber.

4. Using the Calculator

Tips: Measure radius at the middle of the trunk segment. Common wood densities range from 300 kg/m³ (softwoods) to 800 kg/m³ (hardwoods).

5. Frequently Asked Questions (FAQ)

Q1: How do I measure trunk radius?
A: Measure circumference at midpoint and divide by 2π, or use calipers to measure diameter and divide by 2.

Q2: What are typical wood densities?
A: Pine ~500 kg/m³, Oak ~750 kg/m³, Balsa ~160 kg/m³. Density varies with moisture content.

Q3: Does this account for bark?
A: No, for precise calculations measure radius without bark or adjust density accordingly.

Q4: What if the trunk isn't perfectly cylindrical?
A: The formula gives an approximation. For irregular shapes, use multiple measurements or displacement methods.

Q5: How does moisture affect the calculation?
A: Wet wood has higher density. Use appropriate density values for the wood's current moisture content.
