Section Combined Properties

The App calculates the area, second moment area (moment inertia) and moduli of inertia of every component and their combination. The graphical representation and touch-and-drag interface make locating the components easy.
During the drag operation, the app simultaneously calculates the structural properties. Rectangular components can be rotated to any position.

This version (v9) uses metric units (Length in mm).
