Coefficient of Linear thermal expansion (CLTE) = Alpha
Alpha=(change in length)/(original length*change in temp)
=Meters/(meters*Celsius)
=m/mC (meters cancel leaving...)
=1/C
=C^-1

∙ 7y agoA small coupon of the material is placed in a thermal chamber and temperature is changed; a laser dilatometer or some other precise device like a linear transducer or capacitor sensor is used to to measure the change in length of the coupon sample. This change is divided by the original length to get thermal strain, which is coefficient of thermal expansion times temperature . Divide by the temperature change to get the effective expansion coefficient over that range. The measurement tool (dilatomer or interferometer or capacitor gage or transducer can be very accurate, better than 10 parts per billion

What is the thermal expansion coefficient for brick?
0.0000055
What is the thermal expansion coefficient for steel c 15?
thermal expansion depends on Temperature and material of steel
What is the cubical coefficient of thermal expansion for metals?
Since most metals are isotropic, the cubical coefficient of expansion is three times the linear coefficient of expansion. The linear coefficient of expansion is obtained from measurement and tables for the specific material which are readily available.
What material has the highest coefficient of linear thermal expansion?
nickel

Linear expansion apparatus?
Linear expansion apparatus is the apparatus used to measure the objects to these following properties: -> coefficient linear expansion -> coefficient thermal expansion -> specific gravity -> specific heat -> thermal conductivity -> thermal resistivity -> breaking strength and many others..
