Centre of Gravity Apparatus
Product Code : JA-ELA-5268
The Centre of Gravity Apparatus (SKU JA-ELA-5268) demonstrates how to find the geometrical centre of gravity of a flat, two-dimensional object. It has a clear perspex rod on a base with a suspension screw at the top and four clear acrylic laminas, one each circular, triangular, square and trapezoidal, with suspension holes round their edges. JaincoLab makes it for school and college physics practicals on equilibrium and the centre of gravity.
Specifications
The apparatus consists of a clear perspex rod mounted on a base with a suspension screw at the top, and four clear acrylic laminas of different shapes with suspension holes along the periphery, as listed below.

Experiments with the centre of gravity apparatus
The centre of gravity apparatus is used to show that a freely suspended flat object always hangs with its centre of gravity on the vertical line below the point of suspension, so the lines drawn from two or more holes cross at that point.
- Finding the centre of gravity of regular and irregular laminas
- Plumb-line method in school physics practicals
- Stability and equilibrium lessons
- Comparing centre of gravity for different shapes
