Plywood load capacity calculator

Plywood load capacity calculator can be used to estimate the maximum load a plywood sheet can support before bending or failing. This calculator assumes a simple bending stress model for demonstration purposes.

Input Parameters

Calculation Formula

Load Capacity (kN) = (Density * Thickness * Width * Length^2) / (12 * E)

Where:
Density = Density of plywood (kg/m³)
Thickness = Thickness of plywood (mm)
Width = Width of plywood (mm)
Length = Length of plywood (mm)
E = Young's Modulus of plywood (Pa)

Results

Load Capacity (kN):

Learn how to use the Plywood load capacity calculator calculator and its working principles

How to Use the Calculator

  1. Enter the thickness of the plywood sheet in millimeters (mm).
  2. Enter the width of the plywood sheet in millimeters (mm).
  3. Enter the length of the plywood sheet in millimeters (mm).
  4. Enter the density of the plywood in kilograms per cubic meter (kg/m³). The default value is 600 kg/m³, which is typical for most plywood sheets.
  5. Click the "Calculate" button to compute the load capacity of the plywood sheet.
  6. The load capacity will be displayed in kilonewtons (kN).

Working Principle

The load capacity of the plywood sheet is calculated based on the formula for the bending stress of a beam. The formula used is:

Load Capacity (kN) = (Density * Thickness * Width * Length^2) / (12 * E)

Where:

  • Density = Density of plywood (kg/m³)
  • Thickness = Thickness of plywood (mm)
  • Width = Width of plywood (mm)
  • Length = Length of plywood (mm)
  • E = Young's Modulus of plywood (Pa)

This formula provides an estimate of the maximum load the plywood sheet can support before bending or failing. It assumes a simple bending stress model and does not account for other factors such as environmental conditions, load distribution, or imperfections in the plywood.
