a metal rod that is 30.0 cm long expands by 0.0750 cm when its temperature is raised from 0°c to 100°c. a rod of a different material and of the same length expands by 0.040 cm for same rise in temperature. a third rod also 30.0 cm long is made up of pieces of each of the above metals placed end to end and expands 0.0550 cm between 0°c and 100°c. find the length of each portion of the composite bars
