Thermal Expansion - Definition
Thermal expansion occurs when there is a expansion occurring due to the heat
The increase in the volume when the temperature increases
Elasticity And Thermal Expansion
When a ball is heated and placed inside some things it could earlier fit in, it wouldn't fit as due to thermal expansion, the ball cant fit anymore
When the ball is cooled and returns to its normal form it can fit inside the thing again
Elasticity Limit
How are we so sure if the ball can still fit inside a circle after being cooled, this is ensured by the calculation of elasticity limit
It's the maximum stress that a material can withstand without permanent deformation.
Stress And Strain
Stress is equal to force / area
Stress = F/A
Strain is equal to Change in length/ original length
Hooke's Law And Elasticity
Formula of calculating thermal expansion requires the temperature, change in length and a constant
Thermal Expansion = a x L x Change In T
A = Coefficient of liner expansion
L = Original Length
T = Temperature
