| Answer: A spring is made of an elastic material
that changes in shape, or deforms when a force is applied to
it. Springs are used in spring balances, also called forcemeters for weighing. A forcemeter looks like this:  Springs are used to store energy in watch and clock springs or door-closing springs. Springs are used to give you a more comfortable ride and are part of the suspension of a car. They also reduce vibration by using rubber blocks. Springs have different shapes depending on what they are used for. A weighing spring, for example, is normally wound as a helix. Watch springs are wound as spiral coils. Sets of flat bars or leaves are used as leaf springs in car suspensions. Switches have springs - think of your lightswitch. Some mattresses and chairs have springs. If you have a certain type of electric door bell, this also has a spring. You might have seen some clockwork toys - these have a key that winds a spring so energy is stored and then can be released. If you have a bike, look at the saddle - does it have springs? To put it briefly, some home uses of springs are: 1. Weighing devices. 2. Clocks and watches. 3. Door-closing springs. 4. Light switches. 5. Electric bells. 6. Mattresses. 7. Chairs. 8. Toys. 9. Car and bike suspensions. |
