Extension Of Springs Apparatus- Engineering Lab Training Systems.
Features Low cost effective teaching Self-contained Wall-mounted
Demonstrates Hooke s Law Measurement of spring stiffness 3 year warranty
Range of Experiments To test the relationship between the load applied
and the change in length of a spring (Hooke s Law) To determine spring
stiffness For more advanced courses, the dependence of spring stiffness
on the wire diameter, spring diameter, length, number of turns and
material. 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
is used to test tension springs up to 200mm in length. 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.
