The online torsion shaft calculator is designed for engineers and designers who need to perform strength and rigidity calculations for shafts under torsion. This tool allows for quick and accurate calculation of maximum shear stresses and shaft twist angles, which is crucial when designing mechanical systems.

Main features of the calculator:

  • Calculation of shaft strength under torsion for various material types, including steel, wood, as well as the ability to input custom materials.
  • Support for different cross-sectional shapes: solid round, hollow round, square, and rectangular tube.
  • The ability to define concentrated and distributed moments, allowing for the consideration of various loads.
  • Graphical representation of results: moment diagrams, twist angle graphs, and stress distributions.
  • An interactive table for editing previously entered section data and moments.

How to use the calculator:

  1. In the "Add Section" area, enter the length of the section, select the type of cross-section, define its geometric properties (diameter, width, wall thickness), and click "Add Section".
  2. In the "Add Moment" area, specify the type of moment (concentrated or distributed), the value of the moment, and the distance from the fixed support to the point of moment application.
  3. Select the shaft material from the suggested list or input your own values for the shear modulus (G) and allowable shear stresses.

After entering all the data, you will receive the results in the form of moment diagrams, twist angle graphs, and stress distributions, as well as a summary table with the key calculation characteristics.

Usage tips:

  • The value of the distributed moment is specified per meter of shaft length.
  • You can modify the values of the sections and moments in the results table.
  • For more accurate calculations, it is recommended to input custom values for the shear modulus and shear stresses.

This torsion shaft calculator allows you to perform complex engineering calculations quickly and conveniently, providing clear graphs and precise results.
