A brass rod with a length of 1.40m and a cross-sectional area of 2.37cm2 is fastened end to end to a nickel rod with length L and cross-sectional area 0.720cm2. The compound rod is subjected to equal and opposite pulls of magnitude 4.28*10^4N at its ends.
Part A Find the length L of the nickel rod if the elongations of the two rods are equal.
Part B What is the stress in the brass rod?
Part C What is the stress in the nickel rod?
Part D What is the strain in the brass rod?
Part E What is the strain in the nickel rod?
