Moment of inertia

•Run the calculation always in a new drawing.

•Drawn elements must be polylines.

•If you have seperated contours, SYSCAD asks for the coefficient of interaction (e.g. 0,70).

Command:

Outer contour:

Select objects: Select the outer contours

Select objects , which should be subtracted:

Select objects: Select the inner contours

SYSCAD can hatch the contour of the polylines. It is helpful to control the correct detection of the contours. In case the detection went wrong we recommend   the manual selection of the inner and outer contours.

Subsequently the material is selected from a dialog box.

Enter the insertion point of the form and fill in the attributes for the form.

In the SYSCAD-Variable / List / form sheet, you can assign different values to 2 variants of the moment of inertia calculation (form Static calculation 1 and 2). You can change the form to suit your requirements.

The following are calculated:

Area - A

Development - EA

Weight - G

Moment of inertia - Jx, Jy

Moment of resistance - Wx,Wy

Edge distance -ex1,ey1,ex1,ex2
