Description
This
apparatus represents the forces in a simple crane and introduces the
student to equilibrium of forces and solution by the triangle of forces.
The crane is mounted on a base designed to be stood on a level bench.
Both the jib and tie include spring balances for measuring the internal forces. A load is hung from the end of the jib.
Re-adjustment
of the crane geometry back to its original unloaded layout is possible
by a knurled adjuster on the jib and adjusting the links of the chain.
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.
