4.A steel rod is heated to 200 degrees Celcius and is then rigidly clamped at both ends and allowed to cool. Determine the temperature at which the rod will break if the tensile strength, coefficient of linear thermal expansion and youngs modulus of
elasticity of the steel are 150MN/m^2, 12x10-6/ degrees celcius and 200GN/m^2
