An iron ball of diameter 6cm and is 0.01 mm too large to pass through a hole in a brass plate when the ball and plate are at a temperature of 20^(@) C . The temperature at which (both for ball and plate) the ball just pass through the hole is (alpha_("iron") = 12 xx 10^(-6) //1^(@) C, alpha_("brass") = 18 xx 10^(-6) //1^(@) C)

A steel scale is correct at 0^(@)C . The length of a brass tube measured by it at 40^(@)C is 4.5 m. The correct length of the tube at 0^(@)C is (Coefficients of linear expansion of steel and brass are 11xx10^(-6)//""^(@)Cand19xx10^(-6)//""^(@)C respectively.)
