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.
