LINEAR, AREA AND VOLUME EXPANSIVITY OF A SOLID GO BACK
LINEAR EXPANSIVITY OF A SOLID
The Lineear Expancivity of a solid is defined as increase in length per unit length for each degree rise in temperature.
Linear Expansivity
Where
= Length after Expansion
= Length before Expansion
The Unit of Linear Expansivity is
Example
What is the Linear Expancivity ?
Solution
AREA EXPANSIVITY OF A SOLID
The Area Expansivity of a solid is defined as increase in area per unit area for each degree rise in temperature.
Where L and B are Length and Breadth of the solid material respectively .
Area Expansivity = 2 x Linear Expansivity
Similarly
Volume or Cubic Expansivity =
= 3 x Linear Expansivity =
