This GUI allows the user to draw different geometric shapes and calculate/display their section properties.|
Three basic shapes can be drawn. These are:
These shapes may be drawn within the axis limits using a mouse left-click for
a new edge and a right-click to close the shape
in case of polygons. In case of a circle, only two points are needed (with left
mouse click). These are the points defining the diameter of the circle.
In case of a square or rectangle, the first and second points indicate the end
points of the diagonal. The first shape is considered
as a basis on which any subsequent shapes the others are drawn as holes. Holes
must lie entirely within the base shape.
In the current version of this GUI, the following properties are calculated and displayed:
- Area (A )
- Center of Area (Centroid) (xs,ys)
- Perimeter (P )
- Area Moments (Ix,Iy,Ixy)
- Centroidal Moments (Iu,Iv,Iuv)
- Polar Moment (Ip)
- Radius of Gyration (ix,iy)
After unzipping, please start the program with shapes_propGUI from the command window.
