Specific weight, wood and timber

This document created by Itieffe is a document dedicated to providing essential information on the density or specific weight of the various types of wood and wood-based materials. This topic is of fundamental importance in several industries, including construction, carpentry, furniture manufacturing and materials science, as knowledge of the specific gravity of timbers is crucial for the design, construction and selection of materials appropriate.

In the paper, we will examine in detail:

  1. Definition and concept of specific gravity: we will explain what is meant by specific weight or density and how this parameter is measured and expressed in relation to wood.
  2. Variety of timbers: We will illustrate the differences between different types of wood and timbers in terms of specific weight. Each wood species has a characteristic density that can vary greatly, and this can affect its suitability for certain applications.
  3. Practical applications: We will discuss the importance of knowing the specific gravity of timbers in real-world applications. For example, how it affects the load-bearing capacity of a structure, the balance of a wooden boat, or the choice of furniture materials.
  4. Measurement and calculation: We will provide information on how to measure and calculate the specific gravity of timbers, including laboratory methods and formulas used.
  5. Variability and environmental impact: We will also consider the role of environmental sustainability in the choice of wood based on its specific weight and the availability of resources.

The main objective of this paper is to provide a comprehensive information resource for those who work with wood and wood-based materials. Knowledge of the specific weight of timber is essential to guarantee the safety, durability and efficiency of structures and products made with this natural material.

Specific weight of wood and wood

“Specific gravity”, also known as density, is a physical quantity that represents the amount of mass of a substance contained in a given unit of volume. In other words, specific gravity measures how much matter is concentrated in a specific space. It is usually expressed in units of mass per unit of volume, such as kilograms per cubic meter (kg/m³) in the International System (SI).

The general formula for calculating specific gravity is:

Specific Weight=Mass/Volume.

Where:

  • “Mass” represents the amount of matter contained in the object or substance, usually measured in kilograms (kg).
  • “Volume” indicates the space occupied by that mass, usually measured in cubic meters (m³).

Specific gravity can vary greatly between different substances and materials. For example, the specific weight of water is approximately 1000 kg/m³ at room temperature. This means that one cubic meter of water has a mass of 1000 kilograms. Denser materials, such as iron, will have a much higher specific gravity, while less dense materials, such as air, will have a much lower specific gravity.

Knowledge of specific gravity is fundamental in several scientific and engineering disciplines, as it affects various aspects, including the load-bearing capacity of structures and the choice of materials in specific applications.
