Centre of gravity - calculation

To study bases of mechanics, we recommend you to choose one of the following web sites.
If you need to explain some mechanical variable, you can use this dictionary.

To solve this exercise, you will need to know both coordinates of partial centers of gravity of all segments, so we advise to draw a picture, where you will paint partial centers of gravity od all segments - see example. After entering all values the calculation of total center of gravity is done according to presented formulas.

Enter weight (kg): m =
Enter height (cm): v =

Segment X coordinate of the segment Y coordinate of the segment
