Description
Shear
legs are often used to make temporary cranes. In this experiment the
ideas developed in experiments with several forces in one plane are
extended to three dimensions. Clarity of thought is encouraged, since
there are both compressive and tensile forces present.
The double
shear legs are mounted on rollers which run on a round bar. Compression
forces in the legs are measured with integral spring balances, and
restraint is by an adjustable tie chain. The back stay is adjustable and
is also fitted with a spring balance. Loading is by a weight hung from
the apex.
The unit is free standing on a bench top.
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.
