A steel rail 30m long is firmly attched to the rod bed only at its ends. the sun raise the temperature of the rail by 500 C causing the rail to buckle. Assuming that the buckled rail consist of two straight parts melting in the centre, calculate how much the centre of the rail rise?(coefficient of linear expansion of steel=12*10-6)
