a.) An aluminum rod has an initial length of Lo = 670 [mm] and has an initial temperature of 24.5o. At what value should the temperature be raised such that the rod would expand at a length of 672.01[mm]? The coefficient of thermal expansion of aluminum is 23.80x10^-6 Co.

b.) Three rods made of copper, aluminum, and brass has the same initial length Lo. All rods expand to the same final length L when subjected to change temperature. Which of the three rods experienced the greatest temperature change?

Copper, Aluminum, or Brass?

Consider two thin rods, one of aluminum and another of unknown material, x of equal length, 100 cm each, both at 12 C. The coefficient of linear expansion for Aluminum is 2.4×10–5/oC. When both having identical initial temperature 12 C are raised to the same final temperature 92 C, the aluminum rod changed in length by an amount that equals double the change happening to the other unknown rod, x. Find the coefficient of linear expansion for the unknown rod.

An aluminum transmission line with a diameter of 20 mm has an electrical resistance of R'elec= 2.636 × 10-4 Ω/m and carries a current of 700 A. The line is subjected to frequent and severe cross winds, increasing the probability of contact between adjacent lines, thereby causing sparks and creating a potential fire hazard for nearby vegetation. The remedy is to insulate the line, but with the adverse effect of increasing the conductor operating temperature. (a) Calculate the conductor temperature...
