7. Consider a cylindrical aluminum rod with a length of 4.945 meters, and a radius of 0.7362 centimeters. The density of aluminum is 2700 kg/m². a. (3 pts) What is the volume and mass of the rod? b. (3 pts) The rod starts out at a temperature of 15.17° C, but is heated up to 223.25° C. How much does the rod lengthen? The coefficient of linear expansion for aluminum is 25 x 106 (°C). c. (4 pts) Explain why the rod expands when you increase its temperature. Include a definition of temperature different from the one in Question 6. d. (4 pts) How much force would you have to apply to this rod to get it to lengthen the same amount as the temperature change in part b did? The elastic modulus for aluminum is 70 x 10' N/m.
