Description
The
centre of gravity of a shape of uniform thickness can easily be found
by this method. It provides a simple technique for complicated shapes,
far quicker than by using calculus for example, although not producing
an accurate answer to the handling of a yacht, the calculation of the
moments caused by the wind and water acting at the 'centre of lateral
area' of the sails and keel are still used as a starting point.
A
free standing backboard has a pin 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.
This equipment is part of a range designed to both
demonstrate and experimentally confirm basic engineering principles.
Great care has been given to each item so as to provide wide
experimental scope without unduly complicating or compromising the
design. Each piece of apparatus is self-contained and compact. Setting
up time is minimal, and all measurements are made with the simplest
possible instrumentation, so that the student involvement is purely with
the engineering principles being taught. A complete instruction manual
is provided describing the apparatus, its application, experimental
procedure and typical test results.
