The cast iron clutch hub and aluminium shaft shown in Figure 4 are cooled from room temperature (20°C) to -100°C. The coefficients of linear thermal expansion of cast iron and aluminium are 11.8x10-6 and 23.0x10-6 °C-1 respectively. Calculate the allowance between the two parts at -100°C for the maximum material condition, to the nearest micron. a. 47 b. -12 C. 23 d. -8 e. 3 F. None of the above
