(22%) Problem 5: A steel ruler is calibrated to give accurate measurements at room temperature. The ruler is used to measure a rod made of unknown material. The rod measures L at room temperature and L+d after the ruler and rod are both heated by AT. The average coefficient of linear expansion of steel is as 50% Part (a) Which object has the larger coefficient of linear expansion? Rod Correct! > * 50% Part (b) What is the average linear expansion coefficient of the rod (ar) in terms of given quantities?
