A solid metal sphere of diameter D is spinning in a gravity-free region of space with an angular velocity of ωi. The sphere is slowly heated until it reaches its melting temperature, at which point it flattens into a uniform disk of thickness D 2 . By what factor is the angular velocity changed? (Give your answer as a factor of ωi.)
