## Homework Statement

i came across this question while revising, can someone talk me through it please. I need to calculate the dimensional change.

The stator of an electric motor winding is to be expansion fitted into its housing. if the diameter of the stator at 20 degrees C is 150.1 mm and the diameter of the housing is at 20 degrees C is 150 mm, determine the temperature to which the housing must be raised to facilitate the assemble.

The coefficient is 12x10 ^-6 degrees

## Homework Equations

∆L/L = α∆T, α is linear thermal expansion coef
