|Springs are available in
a large variety of shapes and sizes. Almost everyone will have either used
a springboard at a swimming pool to dive into the water. The springboard
may be made from laminated wood (layers of wood glued together) or be a
more modern glass fibre type material. The result is the same - the diver
uses his/her weight to spring off the board into the air.
Springs have a very wide range of uses and it is difficult think of a mechanical device without one or more of them.
|Springs perform different actions and some examples are seen below. Some restrict stretching whilst others restrict compression.|
|Springs are used in engines, motors, watches, clocks, door handles, locks, pens etc... Choose a simple mechanism and dismantle it. Study how any springs work and draw a diagram to represent the movement involved (add explanatory notes).|
|List three materials that possess the property of ‘spring’ and describe a practical application (example - a plastic ruler manufactured from polyethylene).|
|MAIN TYPES OF SPRING|
|Study the three main types of spring shown below. Using the internet research each type. Describe and sketch a practical application of each type.|
