An app to calculate geometric properties of sections

We describe the functionality of the ShapeSurf app.

The app calculates the Geometric Properties of various kinds of plane sections without having to carry a printed book.

You can use this app for:

  • engineering analysis and design
  • stress analysis
  • to calculate the natural frequencies and mode shapes of a machine element
  • students

The app has an intentionally simple interface and the typical sections you would find in a reference book.

As a result the app gives the geometric properties of a bidimensional shape:

  • Area: the total area of the shape;
  • Centroid or geometric center: X and Y position; the average arithmetic mean of all the points in the shape
  • Moment of inertia about X and Y axis
  • Inferior and superior section modulus, also called moment of resistance.

Most noteworthy the user can export the output with a csv file attachment.
