Application of Expansion in Everyday Life Some of the benefits of
expansion are frequently encountered in everyday life , such as:
a. Pengelingan
Connecting the two plates by using special nails with a special process called rivet . How rivet installation ? Rivets used to rivet something in a state of heat to incandescence and incorporated into a hole that we wish to rivet plate . Then nail the top pounded until smooth . After chilling the Rivets will shrink and
Press firmly with the plate . Pengelingan you may have encountered in the manufacture of marine hull .
b . bimetallic pieces
Two pieces of metal that has a different coefficient of expansion length pieces riveted together called bimetal . Chips bimetallic sensitive to temperature changes . If the pieces bimetal is heated, it will curve to the metal figure expansion coefficient smaller length . When cooled , the bimetallic pieces will curve to the expansion coefficient of the metal which figures large in length . The difference of this expansion is used as a thermostat . The thermostat is a device that doubles as an automatic switch and as
temperature control . Some tools that utilize the puck bimetal thermostats , among other
things : electric irons , ice cabinets , electric bells , fire alarms ,
car or motorcycle turn signal , rice cooker , oven .
c . Mounting frame and metal wheels on the wagon train
Wagon wheel and rail wheel has a smaller size than the size of the frame . To be able to install the metal wheel , then by way of heating . This resulted in a metal wheel will undergo expansion . Then the metal wheels mounted on the frame , when cool wheels will shrink and firmly attached to the frame .
