The stator of an electric motor winding is to be expansion fitted into its housing. If the diameter of the stator at 20 degrees Celsius is 150mm and the diameter of the housing at 20 degrees Celsius is 150mm, determine the temperature to which the housing must be raised to facilitate the assembly if the coefficient of linear expansion for the housing material is 12*10 to the minus 6/degrees Celsius .
