Centre of Gravity

Lifting Lug Lifting Lug

The Darbury COG (Centre of Gravity) program is used to calculate the centre of gravity of multiple objects in a 3D design space. The user identifies either the size of a baseframe, or the size of a limiting rectangle to be considered, then adds the point loads on to the screen to represent the relative weight & positions of all objects needing calculating. The relative positions are shown in a simple to read image & the calculation can be processed with the touch of a button.

The program prints a complete computation, including the 1st principles of the calculation complete with a diagram of how the dimensions are to be read.
