The Centre of Gravity Apparatus is an effective and economical tool designed for the demonstration of the geometric center of gravity in two-dimensional objects.
\n
This apparatus features a PVC rod mounted on a stable base, equipped with a suspension screw at the top.
\n
It includes four clear acrylic laminas, shaped circularly, triangularly, quadratically, and trapezoidally, each containing suspension holes along their peripheries.
\n
When lines are drawn from the suspension points of two or more holes on a lamina, the intersection of these lines indicates the centre of gravity for that particular shape.
