Comparison with theoretical estimate.
Description
Springs
are used in engineering to store energy or to provide restoring forces.
Both compression and tension springs may be encountered. The deflection
of a spring depends on the load applied to it, an observation enshrined
in Hooke's Law. Applications of springs are found in spring balances
which indicate loads by measuring spring deflections and in car
suspensions where they absorb energy caused by wheel vertical movement
due to potholes and bumps.
The equipment is designed to be fitted
to a wall. It can use compression springs up to 150mm long. The maximum
spring diameter is 38mm.
A weight hanger is used to apply a load
to the spring. Spring deflection is measured with a sliding scale which
can be easily re-zeroed to suit the length of the spring. A spring,
weight hanger and weights are supplied with each piece of equipment.
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.
