Expansion

Explanation:

Expansion is the change is size of a body with increasing temperature and tension.

Bridges are built of iron. Iron thermally expands in the presence of increased temperature during the day. The length of the iron will increase by simple fractions. At night, when temperature drops, the bar returns back to its initial position.

  • The allowance for expansion of the metal is made in order to prevent tension within the structure.
  • Not doing this will cause the material to break since there is no free space for the bar to change shape.
