A steel sphere is to be passed through a circular brass ring. At 20°C, the outer diameter of the sphere is 25 cm and the inner diameter of the ring is 24.9 cm. If both are heated together, find the temperature at which the sphere will just pass through the ring. Given : αsteel = 1.2 × 10-5 °C-1 and αbrass = 2.0 × 10-5 °C-1.(Show the working).
