Area Moment of Inertia Lite

This tool helps to calculate moment of Inertia for any open, closed, cut, holed cross section. Area, principal or 2nd moment of inertia (MI) is the sectional properties of 2D shapes. These are useful for structural mechanics and dynamics performance prediction. Cross Sectional properties are important for tension and compression performance calculations. Moment of inertial is critical for bending stiffness and strength calculations. MI properties for a standard shapes can be obtained from a list of table or standard formula. But for irregular shapes and nonstandard sizes, the sectional properties are not readily available. This tool allows you to draw any shape and then calculate geometric and inertial properties for any arbitrary shape. Geometric and MI properties of any regular/ standard shape can also be predicted. Draw non intersecting outer by tapping the vertex of your 2D shapes. You can also create a hole or cut by tapping the vertex of your cut or hole. Then click “area MI” to calculate the Sectional properties. The default drawing window size is 2 mm and snap size is 0.02 mm. You can change by tapping the settings. You can also edit the X,Y coordinates of the vertex for more accurate input. Select your convenient Units. Set the window size to the maximum size of your 2D shape. This size can be set to any size from nano meter (10-9) to giga meter (10 9). Area MI lite tool supports any shape bounded outer by straight lines. Draw by tapping the vertex in clock wise or counter clock wise pattern. Avoid crossing of the boundary. The end point can be closed by tapping close end. Clear, Undo, Edit and CloseLoop buttons are useful to start with any shape, edit the vertex to change shapes, add lines, or move lines and or close the boundary. The second moment of inertia is a measure of the
