A steel rail 30m long is firmly attached to the roadbed only at its ends. The sun raises the temperature of the rail by 50⁰C, causing the rail to buckle. Assuming that the buckled rail consists of two straight parts meeting in the centre, calculate how much the centre of the rails rises. Coefficient of linear expansion of steel is 2×10^-6 /K
