(Product number: HFC8)
The centre of gravity of a shape of uniform thickness can easily be found by this apparatus. It provides a simple technique for complicated shapes, far quicker than using calculus for example.
A free standing backboard has a hook from which a selection of flat shapes can be hung. A simple pendulum suspended from the pin enables the line of action of the weight to be transferred to the lamina. The centre of gravity is the position on the shape where two or more such lines intersect.
6 different shapes are provided, each having a number of holes in their profile. This allows for the shapes to be suspended at different points, and the lines of action drawn.
