Description
The
apparatus consists of a jib restrained by two chain ties making a
triangulated three dimensional structure. The jib and both ties are
fitted with spring balances so that the internal forces can be measured.
The
bottom of the jib is pivoted to the wall mounted plate and the tie
attachment locations can be varied independently at their wall ends.
A
load is hung from the jib end, and the geometry returned to its
unloaded state using a knurled collar before taking the spring balance
readings.
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.
