A cylindrical brass sleeve is to be shrink-fitted over a brassshaft whose diameter is 3.214 cm at0°C. The diameter of the sleeve is 3.202 cm at 0°C.
(a) To what temperature must the sleeve beheated before it will slip over the shaft?
°C
(b) Alternatively, to what temperature must the shaft be cooledbefore it will slip into the sleeve?
